SOLVERS: Nonlinear Static Settings
Description
The Nonlinear Static solver determines the behaviour of structures by taking into account three main types of nonlinearity:
- nonlinear geometry; this accounts for structural stiffness that changes as the structure deforms, and therefore the displacement will not be proportional to the applied load;
- material nonlinearity; this accounts for materials that do not obey Hooke's law; and
- boundary nonlinearity; this accounts for contact between components or between a component and a rigid boundary.
This solver also considers staged construction analysis (Global: Stages).
This solver does not consider time-dependent effects such as inertia or damping, but does offer the option to assign a pseudo time to each load step for the purpose of using time-dependent material properties on a step by step basis.
