Hello,
I have a table (x,y) contains 2020 measured values (stroke sensor). I would like to calculate the area under the curve. Can i do it with Matlab(or Excel).
Thanks
Rob, thanks for your answer!
I tried to use adaptive re-meshing but i have a error message about the "error variable"
--> no error variables are valid for the selected step type
hello,
I simulate a mechanical joining method "clinching": 2D Axisymmertic in Dynamic Impl
I try stamping two sheets (deformable) whit a punch rigid. I used simple contact friction 0.2
During the simulation the edges in the end of the sheets don't move. The stress around the punch becomes...
Hello,
I study a damage problem (Dynamic-Temp_disp Exp) between a tack (nail) and two sheets. At th end of the simulation there is no damage on the sheets
Tack is analytical rigid
Sheets are deformable
I use a JK platicity and a JK damage
Thanks
Hello MatthewM23,
Pure bending is an elastic solution. For me, you don't need a plastic behavior. But if you want to use the plastic behavior of material, I would advise you to use the linear plastic (ex 262 0, 282 0.1) it' s better for elasto-plastic simulations.
You may improve your...
Hello,
I did same BC modification. It could be useful for your simulationhttp://files.engineering.com/getfile.aspx?folder=db4a0a7b-0ee8-4075-afda-dcb6293b6436&file=Control_vf1.cae
Hello,
The normal contact definition is not needed. You can simulate a contact with only tangential contact

Hello,
I can not open your CAE (you are using abaqus 6.14 and I have abaqus 6.13).
If you are doing a displacement control to get Disp-Force curve you must represent Reaction Force (RF) in the reference point according the displacement.
Maybe you have forgotten to activate NLgeom in step.
Try with "Model_1_Transite" http://files.engineering.com/getfile.aspx?folder=099fb97c-293f-4ed2-8692-7b679215d9http://www.eng-tips.com/viewthread.cfm?qid=388437c5&file=essai_2.cae
If you want to cool about 16°C your part1 you can change time period (ex. 10000 50000 ...)
or Model_1_steady_state...
>If you create a temperature condition in BC, you can see any variation.
>I think you mean can't, right?
Yes, "If you create a temperature condition in BC, you can not see any variation" Sorry!
hello,
Density
Thermal expansion, T(°C)
Yield stress, T(°C) (f you need to study plastic behavior)
Specific heat, T(°C)
Young’s modulus, T(°C)
Thermal conductivity, T(°C)
hello,
You can do your simulation into two steps , in a first step you can apply u2=10mm, deactivate it in a second step and you can create a bc displacement in step2.http://files.engineering.com/getfile.aspx?folder=9b9ca662-39c8-496a-9b71-bc8b45acdd58&file=Sans_titre.png
Hello ,
I try to simulate quenching of a steel strip with abaqus standard, the step is coupled temp-displacement
I can’t find the balance energy between internal energy and work external. In my model ALLWK is very excessive
ETOTAL is not constant, it increases. I don't understand why it is...
Hello,
I m analyzing the rapid cooling (about 700C°C/s) of steel plate (thickness 1mm) in Abaqus/Standard.
I have same convergence problem like :
***ISOTROPIC HARDENING PLASTICITY DID NOT CONVERGE FOR ELEMENT PLATE-1
***THE SYSTEM MATRIX HAS 6 NEGATIVE EIGENVALUES
I tried
- reduce the...
hello,
You can use an amplitude tabulor.
example if u have 1000mm/s
Time/frequency Amplitude
0 0
0.030999828 31 --> d/t = 31/0.03099828 =1000mm/s
0.080999828 81 --> d/t = 81/0.08099982 =1000mm/s
0.130999828 131
0.180999828 181
0.230999828...
Hello,
I m using the subroutine dflux for a simulation Abaqus Standard (coupled temp-disp). I would like to do this simulation in a dynamic Temp-disp Explicit step.
I would like to know if it possible use the subroutine dflux in explicit. And what are the modifications i have do in dflux to...
