The Composites Affordability Initiative (CAI) unanimously selected ESRD’s composites functionality to “replace as well as radically improve existing industry software currently used for bonded joints.” In time, the improvements extended to fastened laminated composite and metallic-laminated joints, reinforced composite structures, multi-scale analysis and more.
Instead of plate or shell modeling, we focus on the important details, such as interlaminar failure modes and thru-thickness ply stresses.
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.

When performing parametric structural analysis, ESRD’s p-element StressCheck® FEA software is always my preferred choice due to the excellent solution quality, parametric framework, and superior computational efficiency. In fact, I recently used StressCheck® to generate stress intensity factors along a parametrically defined elliptical crack-tip across 3,000 unique geometric configurations. Considering multi-body contact was present and all simulations were performed using a laptop, this was a task well suited for StressCheck®.
