Composite Stiffness Property Prediction

07 Aug 2017 | Downloads

Micromechanical models for the composite axial tensile, transverse tensile, and axial shear are combined into one tool with the objective of comparing their effectiveness as property prediction methods.  Rule of mixtures models (ROM) and the composite cylinder model (CCM) results for...

Computational evaluation of effective stress relaxation behavior of polymer composites

11 Jul 2017 | Publications

This paper presents a micromechanics model to characterize the effective stress relaxationstiffness of polymer composites. The linear viscoelastic behavior of polymer material wasmodeled by hereditary integral. The proposed model was established based on thevariational asymptotic method for unit...
