Nodal stress and strain history output from Abaqus

Submitted by handsome on

Hi everyone,

I am trying to get the history output of
strain and stress tensor components at a node. However after analysis is
finished no such data are saved in the result section. I think Abaqus
only gives the stress and strain for elements and not at nodes. Any help
would be highly appreciated. Please consider that I am a new abaqus
use.

Thank you in advance

What are the differences between increment strain defined by dstran and dfgrd0,dfgrd1 in abaqus?

Hi everyone,

   I am used to use 'dstran, stran, drot...' to develop my user subroutine UMAT and VUMAT codes in Abaqus. But recently I read some publications in which they use dfgrd0, dfgrd1 and dtime to develop their codes. I want to know what are the differences between these two ways?

   Thank you very much!
