Applications & Simulations

ESRD has been helping aerospace and defense (A&D) engineering professionals solve the toughest problems in strength, durability and damage tolerance of metallic and composite structures since 1989.

We developed the world’s premier high-order FEA tool, StressCheck Professional, to empower our customers to obtain reliable solutions to their challenging engineering applications.

What Are Your Engineering Analysis Goals?

Are high-resolution stress or strain gradients important to you? Or, any of the following?:

  • Stress concentrations for small and/or difficult to analyze features
  • Adhesively bonded ply by ply laminated composites details
  • 3D stress intensity factors (SIF) for user-defined crack geometries
  • Multi-body contact analyses of fastened joints
  • Residual stress due to cold-working process
  • Global-local analysis of airframe details
  • Customized engineering simulation apps

If so, then there is a high probability that we can help you achieve your present (and future) simulation goals with our software products.

Application & Simulation Focus

The following section highlights key engineering applications, and related solid mechanics problem classes, that are well-suited for ESRD’s numerical simulation technology:

Learn More 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. Residual Stress Applications

Testimonials

  • “StressCheck is the work horse for NAVAIR Structures’ detailed stress and stress concentration calculations. This software also is the basis for our development of a Structural Analysis Management System.”

    Dr. David John Barrett, Head
    Airframe Technology Branch, NAVAIR

Testimonials

“Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”
