Static Stress Analysis with Linear Material Models
Static stress analysis with linear material models is the most common
type of FEA. It enables the study of stress, strain, displacement and shear
and axial forces that result from static loading. This type of analysis is
often sufficient for situations in which loads are known and the time of
peak stress is evident.
Engineers apply static loads (such as forces or pressures) or known
"imposed" displacements to a finite element model in a linear
static stress analysis. They then add elastic material data, constraints and other information such as the direction of gravity. Static
forces are assumed to be constant for an infinite period of time while
resulting strain, movement and deformation are small. Engineers assume that
the material will not deform beyond its elastic limit and that any resulting
dynamic effects from the loading are insignificant (i.e., inertial effects
can be neglected), known as mechanical equilibrium.
