A method coupling experiments and simulations, is developed to characterize the yield stress strain hardening of several metals loaded at 106 s?1 < 25 ns, typically involved during Laser Shock Peening. It was applied four materials: pure aluminum, 2024-T3 7175-T7351 aluminum alloys Ti6Al4V-ELI titanium alloy. Thin foils have been irradiated with high-power laser induce high-pressure shock wave....

Abstract The pure titanium, as a biomaterial destined for production of load-demanding prostheses, requires thermo-mechanical processing to increase its strength. most common way achieve this is the method grain fragmentation. Thermo-mechanical deformation titanium complex process, which makes it very difficult describe by means constitutive equations. Such relations are useful they can be impl...

Electromagnetic forming is a high energy rate forming process. In this process, an electromagnetic Lorentz body force is used for deformation of products. In this article, Electromagnetic forming process was simulated for assembly of parts as an innovative method. In this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

This research focuses on the study of simulation capabilities lagrangian (LAG) model and Smoothed Particle Hydrodynamics (SPH) for orthogonal dry machining aluminum alloy Al6061-T6. A three-dimensional finite element was developed verified using experimental data from published literature. The numerical models were boundary conditions via modeling in ABAQUS/Explicit 6.14. cutting simulations ca...

Abstract Phase separation and coarsening is a phenomenon commonly seen in binary physical and chemical systems that occur in nature. One model which takes into account additive stochastic noise is the Cahn-Hilliard-Cook (CHC) model. Often, the surface on which phase segregation occurs is not a flat surface. With this motivation, we present a semi-implicit numerical algorithm to solve the fourth...
