Computer Aided Design Environment for Composites (CADEC), a cloud-based engineering software application hosted by the Mechanical and Aerospace Engineering Department at West Virginia University (Morgantown, W.Va.), has been updated. The application performs micromechanics for composites reinforced with unidirectional fibers, random fibers and plain-weave, twill and satin textile fabrics. Predicted properties include lamina moduli, strength values, coefficients of thermal expansion (CTEs) and moisture expansion. Its laminate analysis capabilities include stress, strain and failure, and its failure predictions encompass first-ply failure and last-ply failure under mechanical, thermal and moisture loads. The failure predictions include in situ effects and model failure criteria, such as those proposed by theorists Hashin and Puck. Another feature is the comprehensive analysis capabilities for laminated composite thin-walled beams with general cross-sections. The beams can be asymmetric and loaded by general combinations of forces in three planes (axial, vertical and horizontal) and by three moments (torque and two bending moments). The software computes all the section properties, including the shear center. Data integrity enables users to refine the properties of any object (e.g., fiber properties), and the software will automatically and transparently update all the dependent objects, such as laminates and beam sections. User-created objects are stored in an encrypted database. Prospective licensees can test the software by downloading a 30-day demo subscription.
