| Summary: | A three dimensional finite element program has been developed for the purpose of conducting linear uncoupled thermoviscoelastic stress analysis. The primary motivation behind this development has been to enable the accurate analysis of laminated polymeric composite structures subjected to a high temperature environment. The program is written to serve as a general purpose tool, suitable for predicting the response of an orthotropic viscoelastic composite to a wide range of loading/temperature histories. Phenomena such as creep, relaxation, and creep-and recovery can all be predicted using the program. Of particular interest has been an application of the code to the analysis of a matrix-cracked laminate. Numerical (finite element) analysis of a matrix-cracked laminate is compared to an analytical analysis based on the viscoelastic correspondence principle. |
