The Laminator is an engineering program written for Windows XP, Vista, and Windows 7 that analyzes laminated composite plates according to classical laminated plate theory. Familiarity with such analysis is assumed. Input consists of ply material properties, material strengths, ply fiber orientation and stacking sequence, mechanical loads and/or strains, and temperature and moisture loads. Output consists of apparent laminate material properties, ply stiffness and compliance matrices, laminate "ABD" matrices, laminate loads and mid-plane strains, ply stresses and strains in global and material axes, and load factors for ply failure based on Maximum Stress, Maximum Strain, Tsai-Hill, Hoffman, and Tsai-Wu failure theories. A micromechanics calculator is also included for estimating lamina properties for given fiber and matrix properties. The program can also be run from the command line for batch processing.
