Nonlinear Analysis

|
When the material is linear elastic, where the geometry will return to original shape
|
Linear approximation is fast and efficient solution for many engineering problems. However, most of the real life problems in engineering world are nonlinear
|
|
Deformations are small
|
In many cases, simply understanding the effects of nonlinearity can enable the design engineer to make sound design decisions based on linear results
|
|
Loads and restraints are constantly applied to the model, without change in magnitude or direction
|
Even though nonlinear solution runs take longer time, it replicates the actual physical system being analyzed and the test results will correlate very accurately.
