Linear Elasticity Solver

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

  • “Through the use of StressCheck the A-10 Aircraft Structural Integrity Program’s (ASIP) Analysis Group is able to model more accurately the physics of fatigue crack propagation in critical aircraft structure.  Through this tool we are able to model, analyze and predict failure of aircraft structure and then develop crucial inspection and maintenance planes to ensure the safety and sustainability of our nations warplanes.  Without the analysis capability provided to us through StressCheck we would not be able to provide accurate assessments of the A-10 structure to top USAF leadership.”

Testimonials

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”
