Strains and Stress in NonLinear Finite Element Method
Published by October 19th, 2007 in LS-DYNA Bytes. 0 CommentsCame across this nice document that talks about the strains and stress computations used in many nonlinear finite element codes. If you know the author of ths material, please do let me know. You can also find the entire set of materials here
