Incremental Plasticity Technical Brief

Abstract: Material nonlinear problems that involve loading conditions that produce stresses outside the quasi-proportional limit (e.g., sequential loading and unloading with reverse plasticity) can now be solved in StressCheck® using the incremental theory of plasticity (ITP). The implementation of the ITP is rate (time) independent and considers the von Mises yield criterion and the associated J2 flow rule with isotropic/kinematic (mixed) hardening for 3D, plane strain, plane stress, and axisymmetric analysis.

Testimonials

“Of the three FEA products we use, StressCheck^® gives me the most confidence when it comes to performing post-processing quality checks on multi-body contact analysis results. StressCheck^® has the capability to extract any data of interest and convergence information for that data at any location in the model domain; the other two FEA products do not. And when it comes to interference fit multi-body contact solutions, I haven’t found any software to outperform StressCheck^®.”
