I am having problems with large strain viscoelasticity, where I am using Prony series to model the visco part. There is no default for the parameter CETOL, nevertheless, by reducing this tolerance or reducing the time step I am getting results that make no sense.
Hi,
I am new to writing VUMAT. I tested my Neo-Hookean hyperelastic material and the build-in Abaqus material on single element model but got quite different results. Can anyone take a look at my code and let me know if there is anything wrong?
Eigenstrains are created as a result of anelastic effects such as defects, temperature changes, bulk growth, etc., and strongly affect the overall response of solids. In this paper, we study the residual stress and deformation fields of an incompressible, isotropic, infinite wedge due to a circumferentially-symmetric distribution of finite eigenstrains. In particular, we establish explicit exact solutions for the residual stresses and deformation of a neo-Hookean wedge containing a symmetric inclusion with finite radial and circumferential eigenstrains.
Hi friends;
I want to assemble three volumes with different properties in apdl ansys, but ansys ignore CMGRP command when I use it, what's problem my code? How can I assemble three volumes? please help me.
my code is:

Dear Colleagues,
There are a lot of sample UMAT subroutines for plane strain or 3D problems. However, it is difficult to find an example for the plane stress problem online. Even the UMAT manual does not provide enough information. I have tried the UMAT subroutine for the plane stress problem for a while. The following remarks may be useful for collegues who have interest.
1. The stress components σ11, σ22, σ12 should be returned to UMAT. The other three stress components equal to zero, known as the basic assumption of the plane stress problem.
Employment as an assistant researcher (Post-doc) at the project OPUS from National Centre of Science.
hi all,
I am a PhD student .for my research I must ecire a uel to visualize the distribution of moisture in the composite polyester / fiberglass exposed to two different temperatures on both sides with abaqus.
any help is appriciessed
Hi,
I am trying to find the method of stress evaluation used in Isogeometric analysis. I havn't come to know any numerical process for stress computation along with its implementation in IGA. Can someone please help me in this regard.
Thanks -Vishal
