TROY — Altair Engineering Inc., developer of HyperWorks computer aided engineering software, announced the release of StressCheck by St. Louis, Mo.-based Engineering Software Research and Development Inc. in the HyperWorks Partner Alliance.

StressCheck complements Altair’s finite element analysis solver, RADIOSS, supporting detailed structural and strength analyses including multi-body contact and computation of fracture mechanics parameters for metallic and composite parts.

ESRD is renowned in the aerospace industry, but increasing requirements for detailed FEA and stress analysis in mechanical and structural engineering of all types make StressCheck a strategic addition to the HyperWorks Partner Alliance. HyperWorks users will be able to access StressCheck from the HWPA website at

Said Dr. Anil K Mehta, senior vice president of business development at ESRD, Inc.: “StressCheck is well known for its advanced technical capabilities in the aerospace industry. HyperWorks customers, especially in the automotive and turbo-machinery industries, will benefit from its verified stress analysis capabilities, as well as its unique functionalities in laminated composites, fatigue and damage tolerance analyses. StressCheck provides a framework for standardization of simulation practices in a scalable electronic handbook in support of the accumulation and management of expert-designed solutions.”

HyperWorks customers can access StressCheck through the HWPA, a suite of third-party partner applications that can be accessed with the same units used to invoke Altair HyperWorks software. The flexibility of these HyperWorks Units empowers users to deploy the largest and most complete suite of CAE applications available at no incremental cost or long-term commitment.

“ESRD’s StressCheck is a strategic addition to our HyperWorks Partner Alliance,” said Robert Yancey, executive director – global aerospace at Altair.  “Detailed stress and fracture analysis, especially for composite structures, is very important in the Aerospace sector.  Coupled with Altair’s optimization technology, ESRD’s StressCheck will provide a broader set of options to our customers when optimizing the design of metallic and composite structures. ”

The HWPA strives to provide the most comprehensive offering of software applications across multiple relevant domains related to computer-aided engineering. The addition of ESRD further enhances the flexibility of the HyperWorks Units and the overall value of Altair HyperWorks.

Engineering Software Research and Development, Inc. (ESRD), founded in 1989, develops advanced engineering software products and offers professional services in this area. ESRD’s flagship software product is StressCheck, an advanced FEA tool based on the p-version finite element analysis method. StressCheck is a leader among p-FEA structural and strength analysis software and is the only FEA product in existence that was designed to meet the technical requirements of simulation governance.
