Computational evaluation of effective stress relaxation behavior of polymer composites

11 Jul 2017

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...

MUL2-UC Beam modeling of periodically heterogeneous composites

13 Jun 2017

The micromechanics code MUL2-UC is developed to work as an efficient and high-fidelity tool for the computation of the effective stiffness matrix and the recovering of the local fields of periodically heterogeneous composite structures. The main novelty is that higher-order beam theories are...
