This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...

The work is devoted to the surface hardening of covered with thermo and electromechanical hardening, as well vibro-autistic grinding jet-dynamic method. An analysis impact strengthening processing on operational prop-erties coatings was carried out; results experimental studies are presented indicating methodology experiment used equipment devices.

Fluidized bed processing is a relatively novel method for coating metal substrates. A detailed study was carried out into surface property and in micro-structure changes induced by fluidized bed processing. In particular, fluidized bed processing of AA 6082 T6 aluminum alloy components using alumina Al2O3 powder was investigated. Firstly, the build up of Al2O3 films was studied and characterize...

We numerically investigate the stability problem of the injection molding process. It was indicated by Bulters and Schepens Bulters and Schepens 2000 that surface defects of injection molded products may be attributed to a flow instability near the free surface during the filling stage of the mold. We examine the stability of this flow using the extended Pom–Pom constitutive equations. The mode...
