The Weibull stress obtained with the 2 commands (POST_ELEM and POST_BEREMIN) with option SIGM_ELGA for small deformations are compared to the figure below:
The Weibull stress obtained with the 2 commands (POST_ELEM and POST_BEREMIN) with option SIGM_ELGA for the large deformations are compared to the figure below:
Note: in large logarithmic deformations (GDEF_LOG), the macro command POST_BEREMIN uses the specific constraint field \(T\), while the macro command POST_ELEM uses the Cauchy stress field \(\mathrm{\sigma }\) (see [R5.03.24]).
The Weibull stress obtained with the 2 commands (POST_ELEM and POST_BEREMIN) with option SIGM_ELMOY for small deformations are compared to the figure below:
