VUMAT and ALE in ABAQUS
Hi all,
Here I encoutered a error in ABAQUS when I include ALE with VUMAT. When ALE was not included with VUMAT, my job can work well while with the combination of VUMAT and ALE, the job cann't work any more due to a "Signal 8" error. And if I use a built-in material model and at the same time ALE, a job can work. Furthermore, element failure is considered in all of the cases.
Anyone can give some suggetion? Thanks in advance!

ALE in ABAQUS and LSDYNA
Hi all,
Can anyone give a description on the diffrence of ALE in ABAQUS and LSDYNA? And also the difference between r-adaptivity and ALE in ABAQUS. It seems ALE in ABAQUS means the same with r-adaptivity in LSDYNA while “ALE” means diffrently in the two codes.
Thanks a lot!

Strain energy density for a plate under uniform stretch deformation
Can anyone give a definition about strain energy density for a plate? When a plate under a uniform stretch s, some gives an equation like ek=Es2/2(1+μ)(1-2μ), some gives ek=Es2/2. What are the difference of these two definition? Please note both of the cases are for plane stress conditions. If under plane strain conditions, what is the definition for its strain energy density? Thanks for help.
