Designer Linear Viscoelastic Material Properties Tailored to Minimize Probabilistic Failures for Dynamic Composite Creep Buckling

摘要

The dynamic response of linear viscoelastic temperature dependent composite plates is investigated under in-plane compressive loads and normal pressures, and due to thermal stresses and moments. Creep buckling instabilities and probabilities of material delamination failures are analyzed to determine plate life or survival times. Optimum designer materials are studied to minimize deflections while concurrently lowering failure probabilities and extending survival times.
