StressCheck Tutorial: Assigning Laminate Orthotropic Materials
Abstract: Assignment of laminate orthotropic materials to hand meshed elements using Type: Lamina and Type: Laminate-Stack.
- If “Lamina” is selected, the user may utilize the “Angle” field to supply ply orientation values. These values may be the ply angle in degrees, a user defined parameter with the value of the ply angle in degrees, or a ply sequence for sub-laminates (e.g. “0/90/0/90/0).
- If “Laminate-Stack” is selected, the user may assign a laminate stack definition to an element or set of elements using “Ply” (ply-by-ply discretization), “Lump” (homogenized sub-laminate) or a combination of both.

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®.
