Thanks Drej,
I am sorry I cannot get what you said. I think the key point is the displacement controlled analysis. I want to know why the units of force are Newtons in a displacement controlled analysis if the stresses are in MPa.
In fact, I think the units of force are MegNewtons, because...
Hi,
VM201 is the Verification Test of Rubber Cylinder Pressed Between Two Plates.
I noticed the VM201 used a strange unit system where length unit is m, force unit is N but Young's modulus unit is MPa.
/VERIFY,VM201
...
R = 0.2 ! RADIUS OF CYLINDER
!!no unit is given in...
Hi,dericcio,
Would you mind to share your successful experience with a ansys newbie?
Although I understand how to treat the loading and unloading, the convergency to simulate my
indentation problem is very bad.
I like to hear your message more, if you have a similar problem.
Thanks.
Frankly to say, I don't know how to use "Table 48.2 CONTAC48 Element Output Definitions. "
To get FNTOT, I will use "Table 48.3. CONTAC48 Item and Sequence Numbers" by the following command:
ETABLE,FNTOT_lable,SMISC, 1
So would you mind to tell me how to get it by using...
I want to calculate the contact force in the y direction. So I need the normal vector components from Contac48 output data. Could anyone tell me how to get them?
Thanks a lot.
I think I got it.
If load=P for loading step, the load in unloading step should be load=0, not load=-P.
But why cannot I find any explanation in ansys documents?
Did everyone have to do a lots of trials to understand this point?!!!
But I cannot understand the meaning of load = @zero in the last response. For example, if I do a trial for elastoplastic
problem of a cantilever beam with an end load, how can I create the unloading step file?
Many thanks

I am just starting to use ANSYS. I want to simulate indentation cycle of loading and unloading. But I don't know how to use ANSYS in the unloading step. Should I superpose a problem of loading at max load with another problem of opposite load?
Your suggestions or comments are highly appreciated...
Metalguy,
The fatigued structure is stainless steel.
The plastic replica method can provide information about the tiny cracks only on the surface. Even we know these tuny cracks exist, we still cannot say how long the remaining service life of the structure has.
Metalguy,
I suppose I don't know the previous record of the fatigued structure.
Dose it mean we cannot estimate its remaining fatigue life by a nondestruction method in this case?
I want to look for a nondestruction method to evaluate the remaining life of a fatigued structure, because I have to continue to use it after the evaluation test.
Can anyone provide some links or published papers about it?
Thank you in advance.
