StressCheck’s high definition stress analysis results are unlike any other in the industry; once you have used StressCheck’s hierarchic solver and unlimited live post-processing you’ll never want to go back.

Detailed Stress Applications

Learn More

Our implementation is unique in the FEA industry for focusing on the detailed analysis needs of composite designers and engineers, including 3D ply-by-ply modeling and failure analysis.

Composites Applications

Learn More

StressCheck is ideally suited for damage tolerance and forensic engineers who need the best representation of 2D or 3D SIF’s, ERR’s and beta factors for input in sophisticated crack growth simulations, or when analyzing repairs for mitigation of cracks.

Fracture Mechanics Applications

Learn More

In the past, reliably simulating RS effects was challenging due to extreme stress gradients, especially in lightweight components. With the technology in StressCheck, representing rapidly changing stresses over short distances is a breeze.

Testimonials

“As the United States Air Force continues to extend the service life of their aircraft the Aircraft Structural Integrity Program (ASIP) has had to refine the methods it uses to analyze and predict fatigue crack growth. Through the use StressCheck, coupled with AFGROW, we in A-10 ASIP have been able to more accurately model, predict and analyze critical aircraft structure for the A-10 and other types of structure for non-A-10 system managers. This also allows us within the A-10 to more accurately assess risk for decision makers, streamline aircraft inductions into scheduled maintenance and reduce cost for total life cycle management.”
