Abstract: A substantial body of qualitative information concerning highly viscoelastic materials suggests they may be much superior to Newtonian fluids in some lubrication applications. Contrarily, most ...

Abstract: Transient temperature and stress distributions are analytically and experimentally investigated for a butt welded plate of HT36-steel. A two-dimensional thermal FE-model is shown to represent the ...

Abstract: A hydrogen-induced fracture process in the HAZ of a QT-steel weldment is studied numerically. Two-dimensional models are used to estimate the transient distributions of stress and hydrogen during ...

Abstract: An analytical model for diffusion of hydrogen in presence of reversible and irreversible traps in the metal is given. A numerical model for solution of the resulting system of nonlinear partial ...

Abstract: In this paper we developed model of a (3D) Fresnel collector with fixed mirrors and tracking absorber which approximates the optical behavior of a fixed spherical collector (hemispherical bowl). ...

Abstract: Material behavior in wires of 1100 aluminum subject to tensile impact loading is examined. Room temperature behavior is observed over the entire range of the stress-strain relation by observation ...

Abstract: We propose a model where a lattice structure is used within an interface layer of finite thickness. An evolution problem is set and studied to analyze the structural changes within the interface ...
