A mechanics model for the deformation of swirl-mat composites
Swirl-mat polymeric composites are considered as representative materials for application in the automotive industry. This article summarizes a three-year long effort to characterize, model, and predict the deformation of these composites under stress, temperature, cyclic loadings, and the ingress of fluids. The effort involved several hundred characterization tests of various kinds and the formulation of a constitutive model based upon fundamental principles of irreversible thermodynamics and continuum mechanics. The above-mentioned experiments and model development were performed interactively. Subsequently, the model was employed in a predictive manner to anticipate experimental data collected under complex load and temperature histories, as well as to predict long-term behavior from short-term data.
