StressCheck’s Linear Elasticity Solver allows you to test ideas before building expensive prototypes. This can be achieved by validating the model and verifying the result independently of each other through virtual experimentation.
Linear Elasticity Solver
Formulate the model.
Verify the model.
Validate the result.
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
- 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
Recent News & Events
“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.”
