Comparing Isotropic Nonlinear Elastic and Isotropic Plastic Material Models Using Cantilever

In the previous post, the Isotropic Nonlinear Elastic material model was explained in detail.

In contrast to this, the isotropic plastic material model divides the total strain ε into an elastic and a plastic component when reaching the plastic material properties.

ε = ε_el + ε_pl

In the attached example, both material models are compared to each other, using an identical cantilever with identical loading.

The load was increased using the Incrementally Increasing Loading function up to a deformation of 40 cm. The Incrementally Increasing Loading function is explained in this article:
