Abstract: The welding of thin-walled thermoplastic parts by ultrasonic vibrations is often seriously impaired by variability in bond strength along the interface of the welded parts. This study shows that ...

Abstract: The analysis of an inclined plane heat source moving along the surface of a semi-infinite solid is presented. Material passing by the heat source is eliminated from the analysis to simulate ...

Abstract: The development of deformation induced anisotropy in wire drawing operations is modeled with a finite element formulation that incorporates a polycrystalline plasticity model to describe the metal ...

Abstract: A novel experiment has been developed to induce inhomogeneous deformations under simple extension boundary conditions. By appropriate prior cold working of stock material and fabrication of test ...

Abstract: In this work, the superplastic material behavior of Ti-6Al-4V has been correlated with the grain size of the a phase. Because this microstructural state variable is directly observable, the ...

Abstract: A novel experiment has been developed to induce inhomogeneous deformations under simple extension boundary conditions. By appropriate prior cold working of stock material and fabrication of test ...

Abstract: A solution methodology is developed for the simulation of a plastic workpiece deformed by a compliant tool. The solution for elastic tool displacements is based on the Boundary Element Method ...

Abstract: A constitutive model for articular cartilage is developed to study directional load sharing within the soft biological tissue. Cartilage is idealized as a composite structure whose static mechanical ...

Abstract: Motivated by the strong dependence of strain-hardening processes on slip system activity, a slip system hardening formulation that explicitly employs accumulated slip system shear strains and net ...
