DOI: 10.1007/s11043-020-09460-2
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: 10.1007/s12289-020-01587-4
Abstract: Al-Mg alloys have the properties of anisotropy, temperature softening and strain rate hardening in warm forming conditions. The former could be modeled by an advanced non-quadratic yield function. The rate-dependent characteristic could be modeled by… read more here.

DOI: 10.1016/j.compgeo.2021.104208
Abstract: Abstract The goal of this work is to show that the thermomechanical behaviour of soils can be interpreted as rate processes that are controlled by temperature-dependent viscous properties. A simple thermally-enhanced viscoplastic model is proposed… read more here.
