Use this analysis types only where all applied loads are static and all material strains are expected to be in the linear elastic range. Whenever any of the strains produced are expected to be in the nonlinear range of the materials used, a Nonlinear type should be specified.
Static stress with linear material models analysis, enables the study of stress, strain, displacement, and shear and axial forces that result from static loading. This analysis type is often sufficient for situations in which loads are known and the time of peak stress is evident.
When performing a static stress with linear material models analysis, engineers apply static loads such as forces, moments, pressures, gravity, or displacements to a finite element model. The model is constrained with boundary conditions and the material properties are defined. Static forces are assumed to be constant for an infinite period, while resulting strain, movement, and deformation are small. Engineers assume that the material will not deform beyond its elastic limit and any resulting dynamic effects from the loading are insignificant.
