Hello friends Welcome To fread tutorial
0:02
and in this tutorial we are going to do
0:05
F analysis in fread with the help of a
0:09
FM workbench in freead and we will do
0:13
the analysis of this L-shaped joint and
0:16
we will study is deformation and
0:18
stresses in freeat you can also visit my
0:22

description
1:02
I will close this file and I will show
1:04
you from the scratch how you can do the
1:06
same Fe analysis which I have did in
1:12
freead now I will create a new file and
1:17
I have activated part design workbench I
1:20
will create my
1:21
body on my origin plane and on this
1:25
plane XY I will uh create my part
1:32
I will off the origin plane I will
1:34
select the polyline tool and create my
1:38
lshift
1:45
part
1:47
now I will make this
1:52
vertical this and this
1:56
horizontal and this will be the vertical
2:00
now I will give my
2:02
Dimensions
2:05
100 this one will be the
2:12
100 and this one will be the
2:19
30
2:22
30 and now here I apply the
2:28
fillet
2:33
and I will give it
2:42
5mm now I
2:44
will close my
2:48
sketch and I will click on the pad tool
2:52
and I will give it a thickness 5
2:55
mm now on this face I will create the
2:59
two holes
3:13
I will project the
3:21
edges now I will give the
3:27
dimension 30
3:32
and this
3:39
115 I will give this and this
3:46
15 and this and this
3:53
30 now I will give this
3:56
diameter 15
3:58
mm
4:02
and I will make this and
4:05
this
4:08
equal now I will click on the pocket
4:10
tool and remove the
4:14
material now our part is ready for the
4:17
Fe
4:19
analysis so we will switch to the FM
4:24
workbench now we here on the FM
4:27
workbench first we will create a
4:30
container for our analysis where we
4:34
apply the material create the meshes and
4:37
run the results so on here you will get
4:41
an icon known as the analysis
4:46
container and our next step is to apply
4:50
the material to our body so I will
4:52
select my body and click on material for
4:57
solid so here I will select my material
5:02
so in my case I'm going to select the
5:04
steel IC
5:07
45 so once you select the material you
5:09
will get
5:11
its properties so density is a
5:16
780 which means that steel IC 45 is a
5:19
carbon
5:21
steel or I can
5:25
select
5:28
some density up to the
5:32
7850 let's
5:33
see still okay this is the better
5:37
material of density 790 now I will click
5:42
okay
5:44
now we
5:46
have applied the material now we will
5:49
apply the forces and we will
5:53
fix our part at one end so this hole
5:58
will be the fix so here you will get the
6:01
icon constraint
6:02
fix click on ADD select the face so you
6:08
can see that fix symbol has been
6:11
inserted say okay now we will apply the
6:16
forces fix means that this hole is fixed
6:20
either with a
6:22
bolt or any other method either maybe it
6:25
will be welded so this is the fix and we
6:28
will apply the forces to apply the
6:32
forces you will see one icon here
6:35
constrain forces click on it click on
6:38
ADD select the surface so now you are
6:42
seeing the force Direction on the right
6:45
hand
6:46
side if you want to your reverse your
6:48
direction just click on reverse
6:50
Direction so you can see that Arrow has
6:52
been
6:53
reverse but I want to apply the forces
6:57
on this direction so click click on
7:00
okay
7:03
now next step is to apply the mesh so in
7:08
free Cat FM workbench we have a two
7:12
types of the mesh if you select our body
7:16
we can see here two mesh first one is a
7:20
FM mesh from net
7:23
gen and second one is a
7:26
gsh so we will go with the net Zen so we
7:30
will click on it and here Max size and
7:35
second order we will take mark
7:37
it so on Max size we will give the five
7:43
and the second order second order is the
7:46
more
7:47
precise let me explain with the images
7:50
so this first one is a first order and
7:53
we see only four notes but on the second
7:57
order is a tetraedron elements and we
8:01
see number of notes are more as compared
8:04
to first order so in F analysis more
8:09
finer your mesh more precise result you
8:11
will get so we will go with the second
8:14
order and click on the
8:17
apply so you can see that uh mesh has
8:21
been
8:22
created triangular count is a 1 23 0
8:25
notes and other value is given here so
8:29
Tetra how uh tetraedron count is 1535
8:33
which I have shown this
8:36
one so we will click on
8:39
okay and here we are seeing the blue
8:42
tick mark so we will click on
8:45
refresh
8:47
now we have model our body we have apply
8:52
the material we have apply the forces so
8:56
in
8:58
forces here I forgot to apply the load
9:02
so load I will
9:04
apply 500
9:07
Newton click on
9:10
okay
9:12
now we will move to the next
9:15
step and next step is our solving stage
9:19
so here on F workbench you will get an
9:21
icon of a solver click on
9:26
it and now you can see that solver has
9:29
been added double click on it so our
9:33
analysis is a Statics
9:35
so we have selected Statics here and
9:38
click on write in
9:41
file and write is completed and then run
9:45
on
9:47
calculus so our calculation is running
9:50
so once you get this message calculus
9:52
done without an error which means that
9:55
our result is ready close
9:58
it now to see the result double click on
10:02
the calculus
10:05
results so here is our results now we
10:08
will read the results and what are the
10:10
results are showing here first one is a
10:13
displacement so we can see that Max
10:16
displacement is a 7 5.75
10:20
Micron and here is a displacement
10:24
Factor
10:26
so displacement Factor we will keep
10:30
five so five means that uh it is a five
10:34
times more displacement than its actual
10:38
size so if we increase our displacement
10:42
so that you can see that how part is
10:50
deforming so we will keep it up to the
10:53
five
10:54
times so this is the displacement and uh
10:57
you can also get here one miss stress if
11:00
you click on it so you can see that uh
11:04
stress is acting you can get other
11:08
Factor as well like displacement in X Y
11:10
and Z
11:11
directions maximum principal stresses
11:14
minimum principal
11:16
stresses where it is
11:19
acting maximum sheer stresses like
11:24
this now we will on our
11:27
body now uh click on the calculus
11:31
results and click here post
11:34
pipeline from
11:36
results so you can see that a graph has
11:38
been inserted here now click on result
11:41
Pipeline and click on here W
11:46
filter on here R filter mode is a
11:49
Surface field is a
11:51
displacement we are more interested in a
11:54
displacement click on apply and
11:57
okay and
12:00
uh hide this CCX
12:03
results sorry hide this result pipeline
12:08
so now you will have the clear
12:10
idea how much stresses is
12:15
acting and how much displacement you are
12:17
getting with respect to the
12:19
graph now let's
12:23
see what if we make the changes to our
12:27
model so here we have a apply the radius
12:29
of 5 mm now we will change the radius to
12:33
the 5 to 30 mm and we will see the
12:36
results again so for this I will
12:39
activate my
12:41
body go to the pad
12:44
sketch and here I will make it
12:53
30 before that I will uh delete this
12:57
results
13:15
so you can see that uh radius has been
13:17
updated
13:18
here
13:20
now activate our
13:23
analysis and again activate this
13:27
solver and write inp file and uh then
13:31
run
13:36
calculus calculus done without
13:41
error now we will click on the
13:46
results so some graphical issue on uh if
13:50
you see
13:53
perpendicular now here we can see the
13:56
displacement with our actual body
14:05
how it is deforming so we will keep our
14:08
Factor
14:13
five say
14:18
Okay now click on
14:23
the calculus
14:26
results click on post pipeline results
14:30
then click on post pipeline result and
14:32
click on the r
14:35
factor and again in Field section select
14:39
the
14:42
displacement and say
14:45
okay and uh hide this result
14:51
pipeline so you can see that uh our new
14:55
result with a modified radius has been
14:58
updated
14:59
and this FM workbench is very pretty
15:03
handy and you can change the shape you
15:07
can change the material and uh you can
15:10
do multiple calculations based on the
15:13
shapes and material in freead FM
15:16
workbench so this is a
15:19
very simple tutorial on uh FM workbench
15:23
of a L-shaped joint in future I will
15:26
take some more complex FM
15:30
analysis till now you can practice this
15:34
with the help of FM workbench and I will
15:36
provide this source
15:38
file in a video description so that uh
15:41
you can practice it and also visit my
15:45
website Mac nexus.com for articles and
15:48
tutorials on freead I will come with
15:51
more useful tutorial like this thank you
15:54
for watching and thank you for your
15:56
valuable
15:57
