Hi,

I'm presently working on implementing anisotropic yield criteria in LSDYNA as UMAT.

I understand from the LSDYNA documents that effective plastic strain is a default history variable.  So when we code, can we omit the update of effective plastic strain as a history variable? If so, where is it stored and how is it retrieved during post-processing ?

Hi everyone,

I’m looking for a postdoc in mechanics of granular materials.

I’m currently a postdoc at INRIA Grenoble, France (National Institute for Research in Computer Science and Control). My principal research interests focus on granular materials. They include (1) computational mechanics, (2) numerical modeling and simulation with DEM, (3) multi-scale approach and homogenization technique and (4) shock dynamics and nonlinear wave propagation. Here are my three principal publications:

Hello, I am trying to solve structural problem of loaded pipe structure in ANSYS.

I tried two method/way.

First I modelled pipe structure as BEAM element and defined the cross-section.

Secondly, I modelled the pipe structure as Shell element and defined thickness. 

Now during post-processing, I noticed very large deviation in shear force, axial force and bending moment (nearly 3 times more in BEAM model cmpr to SHELL model) 

Hello Abaqus Users,

I need to plot deflection (U3) along y axis when x = 0. How to achieve this in Abaqus?

Thanks and Regards,

Sir/Madam,

How to start to written subroutine coding in Abaqus?I have Abaqus/CAE .Can we written subroutine in this Abaqus/CAE.

Thank you.
