Altair Adds Software To Partner Alliance

TROY — The Troy engineering software provider Altair Engineering said Wednesday it had added CAEfatigue Vibration software to the Altair Partner Alliance for HyperWorks users.

CAEfatigue Vibration is a frequency-based fatigue solver and random response post processor developed by CAEfatigue Ltd. of Churt, England.

CAEfatigue Vibration uses 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 company says 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 Neil Bishop, director at CAEfatigue Ltd. “Lightweighting through optimization and resource pooling both become possible. We are extremely happy to be joining the Altair Partner Alliance, and together we will enable this exciting new technology to reach more customers across all territories of the world.”

Uwe Schramm, CTO at Altair, called CAEfatigue Vibration “a unique solution, bringing the ability to simultaneously perform frequency domain fatigue life calculations and random response analysis to our customers, a capability they have not had in the past.”

The CAEfatigue Vibration random response 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 and 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.

The full functionality of CAEfatigue Vibration is available through the APA, which includes the Random Response, Random Only Fatigue, Full Fatigue and Multiple Random Loads modules.

Available for the past 14 years, Altair’s unit-based licensing system, the Altair Partner Alliance, gives HyperWorks users access to a growing portfolio of applications, making more than 20 in-house-developed applications available by use of a single pool of recyclable HyperWorks units.

Altair also has offered the opportunity for third-party companies to run their own applications under this unit-based system, a collaboration now known as the Altair Partner Alliance. The overall flexibility of these HWUs empowers users via access to the largest, most complete suite of CAE applications available.

Under the alliance, more than 60 additional applications available at no incremental cost or long-term commitment.

An introductory webinar on CAEfatigue Vibration will be held Jan. 28 at 9 a.m. and 1 p.m. Eastern time. HyperWorks users can learn more about the company and download the software at
