This core package allows engineers to perform
a static stress analysis with nonlinear material models
to predict material deflection, deformation and displacement.
This core package also includes static stress analysis
with linear material models; weight, center of gravity
and mass moment of inertia analysis; linear contact;
FEMPRO, an easy-to-use,
single user interface for finite element modeling,
results evaluation and presentation; and a suite of
modeling capabilities.
Springs, connectors and components made from plastic
or rubber are often the subjects of nonlinear static
stress analyses. Damping and mass effects are ignored
due to the absence of motion; however, contact between
parts of a mechanism or among independent parts can
be handled in nonlinear static stress analyses.
Nonlinear static stress analyses produce more accurate
stress results than linear static stress analyses
for models that undergo loading in a concentrated
area, have small features such as a small fillet radius
or have constraints that act over small regions. This
is because linear static stress analyses only produce
stresses based on the initial shape of the object,
whereas nonlinear static stress analyses determine
stresses based on the object's deformed shape under
loading.
