Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Effect of Dislocation Density Gradient on Deformation Behavior of Pure Nickel Subjected to Torsion
, 2017 Gradient hierarchical structures, including grain size gradient, twin density gradient, and texture gradient, are believed to broke up the long-standing dilemma-"strength-ductility trade-off' in materials science.

Proper classes generated by τ- closed submodules
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019 The main object of this paper is to study relative homological aspects as well as further properties of τ -closed submodules. A submodule N of a module M is said to be τ -closed (or τ -pure) provided that M/N is τ -torsion-free, where τ stands for an ...
