Abstract: In this paper, the mechanics of ideal forming theory are summarized for general, three-dimensional, nonsteady processes. This theory has been developed for the initial stages of designing deformation ...

Abstract: A semi-analytical method to predict springback in sheet metal forming processes has been developed for the case of plane strain. In the proposed hybrid method, for each deformation increment, ...

Abstract: In this paper, we describe the stiffness of a grasp as a function of grasp configuration, grasp forces and joint stiffness of the fingers. The effects caused by the change of joint configuration ...

Abstract: Collapse of arteries subjected to a band of hydrostatic pressure of finite length is analyzed. The vessel is treated as a long, thin, linearly elastic, orthotropic cylindrical shell, homogeneous ...

Abstract: Electroosmosis techniques have been used in geotechnical and geoenvironmental engineering applications. However, due to electrochemical changes and gas generation at the electrodes as a result of prolonged application of ...

Abstract: Alternating current (AC) electroosmosis tests, which permit rapid determination of the coefficient of permeability of saturated cohesive soils are described. The testing device was developed to minimize the adverse effects ...

Abstract: Friction-stir welding (FSW) promises joints with low porosity, fine microstructures, minimum phase transformation, and low oxidation compared with conventional welding techniques. It is capable of ...

Abstract: A combined experimental and computational study is carried out on creep crack growth in X20CrMoV 12 1 steel and its weld joint. Crack growth tests are conducted on compact specimens at ...
