Macromechanical Analysis of a Lamina

---

The fourth program conducts the macromechanical analysis of a lamina. The input mechanical properties of a lamina are chosen from the lamina properties database. You can then calculate the stiffness and the compiance matrices, the engineering constants and the strength ratios as a function of the ply angle in tabular or graphical form.

A Quick Example

Consider a typical Graphite/Epoxy lamina, find the optimum fiber angle for a load with the following stress components. Use the maximum stress failure criterion for your analysis. Given the following:

LongitudinalStress = 4 KPsi
Transverse Stress = 2 KPsi
Shear Stress = 1 KPsi

After inputing the given data, Promal produces the following graphical output
