Fully isotropic laminates and quasi-homogeneous anisotropic laminates

摘要

The present invention pertains to the layup of laminates that possesses i. concomitant stiffness isotropy in extension, shear, bending, and twisting; and ii. identical stiffness anisotropy in extension and bending as well as in shear and twisting. Although both laminate layups have distinctive applications as load-carrying structures, the approaches and models that generate these layups are closely related.
