HyperLife Overview

A comprehensive fatigue solutions framework.

HyperLife is an easy-to-learn fatigue analysis software developed on a solver-neutral framework. It provides a comprehensive tool set for durability analysis, directly interfacing with all the major finite element analysis (FEA) and multi-body dynamics (MBS) result files. With an embedded material library, HyperLife offers solutions for fatigue life predictions under static and transient loading across a wide range of industrial applications.

Benefits

  • Easy to learn and easy to use graphical interface to perform Fatigue Life predictions.
  • Solver neutral framework interfacing leading FEA results data.
  • Embedded material database.
  • Specialty module to perform simultaneous fatigue analysis on base material and welded joints according to numerous design codes and guidelines.*
  • Customizable environment to add new or in-house functionality.*

*Beta version in the 2019 release.
