Hello ,

 I´m working in my thesis with abaqus only since 4 months, so I´m quite
new. I have to simulate the welding of two sheets with electromagnetic
pulse process. Under these kind of processes the material is load under
high values of velocity and deformations. Taking into account these
conditions I have chosen three different flow plasticity models:

-Isotropic plasticity model without strain rate with johnson cook damage ductile criterion.

What is the difference between Numerical and Mathematica modelling? Can anyone help?

hi 

I want to model a metal with nonlinear kinematic hardening material in ABAQUS. As i read in its user guide manual there is one option in plastic hardening named combined. I want to know if it is an option for modeling a material for combined kinematic and isotropic hardening or nonlinear kinematic?

thanks in advance

Hello!

I need some help.

How do I derive an equation for the increase in volume when water becomes ice?

It has the same mass, different densitys, but how do I derive the volume change?

Hi,

   Just need help to find out how to read results at intergration points in Shell Elemnts in ansys. I need 5 integration points across the thickness of my model.

Thanks in advance

hello,

      I want to simulate the welding simulation found in manufacturing of welded pipe of big diameters. The thick plates are rolled to desired diameters and then they are welded from inside and outside in that joining point. So i want to ask if the finite element software like ABAQUS and ANSYS can support this kind of simulation or not?? 

Hi everyone!

Hello,

After having implemented the corotational formulation for 3D beams (after Crisfield  90), I am now trying to insert joints between some elements of a structure. I found the article by Jelenic and Crisfield [Comput. Methods Appl. Mech. Engrg. 135 (1996) pp. 211-228] to be a good starting point concerning the "master-slave" approach (my problem is static). However, I don't manage to implement the solution process : I think I have not fully understood the approach yet.
