, the curve is a parabola; and for , the curve represents a perfectly plastic material. Ludwik just described the behavior (Fließkurve) of what we now call apseudoplastic material. In version 5.0 of the COMSOL Multiphysics simulation software, beside Ludwik’s power-law, the Nonlinear Struc...
The default nodes for Solid Mechanics are: a Linear Elastic Material model, Free boundary conditions that allow all boundaries to move freely without a constraint or load, and Initial Values for specifying initial displacement and velocity values for a nonlinear or transient analysis (not applicable ...
then the elastic parts of the structure must contract to compensate. This means that elastic energy is released. The only way the energy can be absorbed is by doing work on the damaged part. If, for a certain incremental displacement
The node Linear Elastic Material is the default material model for the Solid Mechanics interface. The node Free is a boundary condition that allows all boundaries to move freely without a constraint or load. The node Initial Values is used for specifying initial displacement and velocity values ...
