The document discusses virtual manufacturing and non-linear finite element analysis. It notes that virtual manufacturing uses simulation technology, computer hardware, and operating systems to create a virtual lab for product creation and non-linear finite element analysis. This analysis examines the structural behavior, design changes, and effects of changes for a product through the engineering tools.

5. NON LINEAR FEA ANALYSIS
PROCEDURE
There are three major types of non linearities
Material
Boundary
(plasticity,creep)
(contact,friction,gaps,follower force)
Geometric
(deformations,strains)
