Abstract: We consider the nonlinear viscoelastic–viscoplastic behavior of adhesives. We develop a one-dimensional nonlinear model by combining Schapery’s nonlinear single integral model and Perzyna’s viscoplastic model. The viscoplastic strain was solved iteratively using the von Mises… read more here.

DOI: 10.1016/j.ijplas.2019.11.011
Abstract: Abstract This study proposes a micromechanical model based on a modified multi-scale mean field approach that predicts the overall behavior of long fiber reinforced elastoplastic and viscoelastic-viscoplastic composites. The homogenization method adopted is the Mori-Tanaka… read more here.

DOI: 10.1016/j.mechmat.2016.11.004
Abstract: Abstract Thermo-mechanically coupled cyclic deformations often occur in polymeric components subjected to a cyclic loading. In this work, a framework of irreversible thermodynamics at small deformation is presented at first to model the thermo-mechanically coupled… read more here.
