A Model for Predicting Thermomechanical Response of Large Space Structures.
Abstract
A model is being developed for predicting the thermomechanical response of large space structures to cyclic transient temperature loading conditions. The research is being conducted in the following stages: 1) selection and specialization of thermomechanical constitutive equations to be utilized in the analysis of large space structures; 2) construction (where necessary) of coupled energy balance equations (modified Fourier heat conduction equations) applicable to the constitutive models selected in item 1); 3) casting (where necessary) the resulting field laws into coupled and uncoupled variational principles suitable for use with the finite element method; 4) finite element discretization of the variational princicples for several element types; 5) experimentation to determine material properties to be utilized in the constitutive models; and 6) parametric studies of the quasi-static and dynamic response of large space structures undergoing thermomechanically and environmentally degraded material properties.
