Ebook: Introduction to Nonlinear Finite Element Analysis using Optistruct

This study guide aims to provide a fundamental to advanced approach into the
exciting and challenging world of NonLinear Analysis. The focus will be on aspects of
NonLinear Dynamic Analysis. As with our other eBooks we have deliberately kept the
theoretical aspects as short as possible.
The tool of choice used in this book is OptiStruct. Altair ® OptiStruct® is an industry
proven, modern structural analysis solver for linear and nonlinear structural problems
under static and dynamic loadings. OptiStruct is used by thousands of companies
worldwide to analyze and optimize structures for their strength, durability and NVH
(noise, vibration and harshness) characteristics.
In this eBook, we will describe in some detail:

Bolt Pretension
Gasket Analysis
Nonlinear Direct Transient Analysis
Please note that a commercially released software is a living “thing” and so at every
release (major or point release) new methods, new functions are added along with
improvement to existing methods. This document is written using HyperWorks
Solvers 2018.0. Any feedback helping to improve the quality of this book would be
very much appreciated.
