Meaning of different strains in post-processing ?

Recommended Posts

Guest

Hi,

Plastic strain is the strain in which the deformed body does not return to its original shape after the removal of the applied force. The plastic strain value is calculated by the solver whereas the von Mises strain is calculated by the HyperView. HyperView calculates the von Mises strain from the six strain components.

 

vonMises Strain =

computed_results_formula6

 

where:

computed_results_p1, computed_results_p2, computed_results_p3 represent the principal strains as calculated above for a strain tensor.

computed_results_v is the Poisson ratio set to a default value of 0.5.
