Description

A need exists to characterize the thermomechanical behaviors of composite materials for applications involving time-dependent behaviors under the influences of high temperatures, intrusion of moisture, loss, and modification of materials properties as a result of chemical reactions. The morphing structures area involves the potential large deformations of aerospace structural materials under influence of various forms of material re-arrangement and may also involve reacting material systems and shape memory. Constitutive models are sought that are thermodynamically consistent and are eventually suitable for finite element structural modeling. Numerical methods development addresses potential multivalued and nonlinear solution strategies under the restrictions improsed by thermodynamics.
