Laminate Module. This module is packed with features. A library of composite and metallic lamina properties can be used or input your own. A layup of any combination of laminae, at any angle can be created. Global laminate material properties are easily calculated and plotted. The laminate can then be loaded with in-plane strains, stresses, resultants, moment resultants and temperature or moisture loads.
Stresses and strains on the individual laminae, due to the applied loads, can be displayed and plotted. You may select from three laminate failure theories (maximum strain, maximum stress or quadratic) to predict laminate strengths. The "first-ply" failure survey option allows you to quickly assess and plot laminate strength for tension, compression and shear. The "progressive-ply" option predicts ultimate laminate strengths and plots the respective stress-strain curves.
Classical in-plane laminated plate theory is the basis of this module.
