New capabilities for fatigue analysis suite

A Safe Technology product story
Edited by the Engineeringtalk editorial team Aug 19, 2003

The latest version of the fe-safe suite of fatigue analysis software for finite element models offers a substantial increase in speed of analysis as well as incorporating extended capabilities.

The latest version of the fe-safe suite of fatigue analysis software for finite element models offers a substantial increase in speed of analysis as well as incorporating extended capabilities, new optional modules and unique state-of-the-art features.

High temperature, time-dependent fatigue phenomena can now be modelled in fe-safe v.5 using the new thermomechanical creep fatigue module, fe-safe/TMF.

This incorporates a number of effects including stress relaxation, strain ageing, cycle strain rate and variation in damage due to out of phase stress and temperature cycles.

fe-safe/TMF is ideal for the analysis of components in a sustained high temperature environment and complements the unique high-temperature fatigue analysis capability already developed in fe-safe.

A new optional module for the specialist user is fe-safe/rotate.

Fatigue analysis of cyclically symmetrical parts from a single FEA result can be obtained quickly and easily using fe-safe/rotate by taking advantage of their axial symmetry, ideal for the quick analysis of components such as wheels, bearings and clutches.

Default fatigue analysis algorithms are a unique new feature.

fe-safe v5 will automatically select the most appropriate method of fatigue analysis based on the selected material.

The user simply selects the material to be analysed and fe-safe will automatically set the most appropriate fatigue algorithm as default, ensuring that even non-specialist users can use fe-safe with confidence.

The new version of fe-safe will also incorporate Safe Technology's powerful signal processing software, safe4fatigue, as a no-cost addition.

The safe4fatigue functionality includes graphics display, signal preparation, digital filters, amplitude and frequency domain analysis and fatigue analysis from strain gauges and other measured load data.
