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.
Linear Elasticity Solver
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

“At DST Group, we have effectively used StressCheck over the last 10 years to determine accurate stress intensity factors. The results have been used to improve our residual strength and structural life estimates for aircraft in service with the Royal Australian Airforce, including C-130, P-3C and F/A-18 A/B. We have found it to be extremely easy to use and a very versatile code with which to create parametric models.
We have recently used StressCheck to obtain improved stress intensity factor solutions (Improved stress intensity factors for selected configurations in cracked plates and Improved stress intensity factors for a single corner crack at a loaded fastener hole) for five key generic configurations. These transferable parametric results have been published externally. One specific example is the non-linear contact analysis of a cracked, filled fastener hole, with both fastener and remote plate loading.”
