Autodesk Inventor Nastran: Non-Linear Analysis

This training course instructs you in the use of Autodesk Inventor Nastran. The software is a finite element analysis (FEA) tool that is embedded directly in Autodesk Inventor as an Add-In. It is powered by the Autodesk Nastran solver and offers simulation capabilities specifically tailored for designers and analysts as a tool for predicting the physical behavior of parts or assemblies under various boundary conditions. Through a hands-on, practice-intensive curriculum, students acquire the knowledge required to work in the Autodesk Inventor Nastran environment to set up and conduct FEA on part and assembly models.

For this course Non-Linear Simulation is defined as:
Nonlinear simulation captures behaviors that cannot be represented by simple proportional relationships. This includes material nonlinearity (plasticity, creep, hyper elasticity and materials like aluminum), geometric nonlinearity (large deformations and rotations that alter stiffness), and contact nonlinearity (changing interactions such as sliding, or any components that move). These capabilities allow engineers to accurately simulate real-world conditions such as part failure, snap-through, yielding, or complex contact interactions.

Topics Covered in this Autodesk Inventor Nastran Training Course:
  • Prepare simulation models for nonlinear FEA (Part and Assembly files)
  • Activate and navigate the Autodesk Inventor Nastran environment to conduct nonlinear analysis
  • Create, edit, and assign nonlinear material models.
  • Manage the creation, setup, and modification of nonlinear static and dynamic analyses
  • Apply geometric nonlinearity to capture large deformations and rotations
  • Create and refine contact definitions for complex surface interactions including sliding, separation, and impact
  • Define and apply nonlinear loads and boundary conditions
  • Control nonlinear solution strategies such as load stepping and convergence criteria
  • Assign global and local mesh settings appropriate for nonlinear behavior
  • Run nonlinear Autodesk Inventor Nastran analyses
  • Review, interpret, and create result plots for nonlinear analysis outcomes
Prerequisites for this Autodesk Inventor Nastran Training Course:
Students should have completed an Autodesk Inventor Introduction to Modeling course. Students should also have a solid understanding of Inventor Model Simplification found in the Autodesk Inventor Advanced Assembly Modeling course and have a working knowledge of the following:
  • Complex assembly design using Autodesk Inventor
  • Foundational Understanding of Finite Element Analysis (FEA) and Kinematic Motion
  • Mechanical engineering or engineering analysis principles
