Fundamental Topics in Nonlinear Structural Analysis (Self-paced Learning Available)

Course Overview

Nonlinear structural analysis can be one of the more challenging analysis types to perform, but it can also provide the most realistic and reliable results, allowing one to  simulate the real-world behavior of most structural systems. To do so, one must master the fundamental skills necessary to unlock the vast nonlinear solution capability of Ansys Mechanical. Nonlinear analysis begins with being able to recognize the factors contributing to structural nonlinearities and how to build models effectively to account for them.


This course serves as a starting point for anyone wishing to perform nonlinear structural analysis in Ansys Mechanical. It provides a foundation for the solution methodology used in nonlinear analysis, while answering the question, “What causes a structural analysis to be nonlinear?

Finally, it focuses on the most fundamental form of nonlinearity, large deflection.


  • Ansys Mechanical Getting Started: Basics and Beyond the Basics is recommended.

Teaching Method

Lectures and computer practical sessions to validate acquired knowledge. A training certificate is provided to all attendees who complete the course.

Learning Outcomes

Following completion of this course, you will be able to:

  • Identify the sources of structural nonlinearities and use the large deflection nonlinearity to its fullest extent. 
  • Incorporate the most effective mesh, loading, and solution controls to account for structural large deflection nonlinear behavior.
