Exploring Hyperelastic Material Using Ansys Mechanical

December 22, 2021

Hyperelastic rubber materials are used in many critical components, e.g., seals, gaskets, and bushings across oil and gas, automotive, and aerospace industries. Simulating a hyperelastic material requires extra effort as they undergo a substantial deformation, usually more than 50 % and sometimes exceeding 700% of strain value.

About this Webinar

Hyperelastic materials undergo deformations with minor or negligible plastic deformation. These materials are soft in nature, and their stress vs. strain response is nonlinear and monotonically increasing. The components of hyperelastic materials experience large strains. Due to these reasons, we often encounter excessive element distortion error and convergence issues. Modeling such cases usually involves accounting for geometric, material, and contact nonlinearities. Our challenge is to determine the coefficients of the equation used for stress-strain curve generation and characterize our material correctly.

What you will learn

You can conquer these challenges and minimize these extra simulation efforts by choosing the suitable hyperelastic material model, contact settings, mesh, and analysis settings from the start.

In this webinar, you’ll learn how to:

  • Calibrate the material model
  • Select a hyper elastic model and curve-fitting it to available data
  • Discover best practices to handle convergence issues
