DOI: 10.1007/s10443-017-9608-6
Abstract: In this paper, three kinds of constitutive laws, elastic, “cure hardening instantaneously linear elastic (CHILE)” and viscoelastic law, are used to predict curing process-induced residual stress for the thermoset polymer composites. A multi-physics coupling finite… read more here.

DOI: 10.1016/j.cma.2020.112872
Abstract: In all structural models, the section or fiber response is a relation between the strain measures and the stress resultants. This relation can only be expressed in a simple analytical form when the material response… read more here.

DOI: 10.3390/met8121043
Abstract: A numerical method for the precise calculation of temperature, velocity and pressure profiles of the α-β brass indirect hot extrusion process is presented. The method solves the Navier–Stokes equations for non-Newtonian liquids with strain-rate and… read more here.
