Frequency-based methods for estimating fatigue life should prove both efficient and sophisticated for design procedures

HyperWorks users can now download CAEfatigue Vibration, a frequency-based fatigue solver and random response post processor.

Comprised of what are essentially two products in one, the software is both a powerful random response post processor for the frequency domain, and a unique vibration fatigue solver.

It works with mixed random and deterministic loading sources, a process not previously available, to provide fatigue life and damage predictions, as well as several forms of response statistics that were not possible before this code.

The tool contains a wide array of capabilities, including calculation of response statistics such as stress peaks, strain peaks and stress and strain root mean square

HyperWorks parent company Altair suggests that it is “exceptionally fast, easy-to-use and capable of handling particularly large models”.

“Frequency-based methods for response and fatigue life estimation offer the promise of very efficient, elegant and sophisticated design procedures,” said Dr. Neil Bishop, director of CAEfatigue. “Lightweighting through optimisation and resource pooling both become possible.”

The tool contains a wide array of capabilities, including calculation of response statistics such as stress peaks, strain peaks and stress and strain root mean square, the latter of which includes the elastic and plastic components estimated using stress-strain material properties.

The CAEfatigue Vibration fatigue tool efficiently provides fatigue damage/life calculations for components subjected to single or multiple random vibration load inputs. Deterministic loads can easily be mixed with random and static offsets to create complex load inputs.

These capabilities are widely applicable across most industries, with major opportunities in the automotive and aerospace industries.
