Linear Elasticity Solver

StressCheck’s Linear Elasticity Solver allows you to confidently investigate solid mechanics-based modeling concepts before manufacturing expensive prototypes, modifying existing structural details and/or developing novel repair concepts. Why confidently? Because our solver implementation inherently separates modeling errors from numerical approximation errors, helping you simplify the engineering decision-making process.

StressCheck increases DOF on a fixed mesh, making solution verification simple, accurate, fast, efficient & reliable.

The Linear Elasticity Solver is the initial building block of the seamless hierarchic modeling framework that constitutes the foundation of StressCheck. Sequential linear elastic solutions are obtained automatically by increasing the polynomial level of the elements, and subsequent advanced analyses use linear solutions as a basis.

Key Features and Advantages

  • Solutions can be obtained by p-extension and adaptive-p methods with convergence-based criteria
    • Allows for easy verification of results without mesh refinement
    • It is simple and easy to extend a linear elastic solution to higher p-levels
  • Multiple solutions can be obtained for the same mesh and convergence in the data of interest can be checked by increasing the number of degrees of freedom (DOF) by p-extension.
  • Includes support for multi-body contact analysis, with no inherent limit on assembly size
  • Solutions on the order of 50 million DOF or more can be computed
  • Provides product development professionals with the most widely used and needed analysis capabilities for structural analysis
  • Identify problem areas and test ideas virtually before building expensive prototypes and experimental fixtures
  • Powerful and extensible – this is the prerequisite module to run advanced analysis types (e.g. nonlinear, margin check, cold-working, modal/buckling)
  • Supports planar (plane stress, plane strain), extruded, axisymmetric, and 3D elasticity analysis

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.”

Testimonials

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
