Macromechanics

Macromechanics refers to calculations in chapter 6, namely laminate calculation of strain, stress, deformation, modulus, moduli, and so on. For strength calculations see Chapter 7. Laminate analysis capabilities include calculation of laminate stiffness, stress, strain, and failure. Laminate analysis can be performed on intact and degraded laminates. The intact material is the undamaged, virgin material, with properties specified by the user. After certain load, which can be predicted in failure analysis, the laminate damages and becomes degraded. For each, intact and degraded, the user can query laminate thermal stresses, laminate coefficient of thermal expansion, laminate stiffness matrices for membrane [A], membrane-bending coupling [B], bending [D], and transverse shear [H], as well as their conjugate compliance matrices. With these, the software can calculate stress from user supplied strains or vice versa. Also, the software can predict the laminate moduli, which are orthotropic material equivalents for the stiffness of the laminate in both bending and membrane modes of deformation.
