Abstract: In this paper, the b oundary e lement m ethod (BEM) approach is used to analyze the thermal aspects of steady state metal cutting processes. Particular attention is paid to modeling of the ...

Abstract: Strength degradation of the finished part due to surface and sub-surface damage is a critical issue in grinding of ceramic materials. In this paper, the chip formation process is modeled as ...

Abstract: A Boundary Element Method (BEM) formulation for the determination of design sensitivities of temperature distributions to various shape and process parameters in steady-state convection-diffusion ...

Abstract: Forming limits of thin sheets are investigated using a yield criterion recently proposed by Hill (1993). This criterion utilizes five independent material parameters, which can be determined from ...

Abstract: The purpose of this study is to determine analytically the orientations of localized necks occurring in sheet metal forming processes, and obtain the corresponding forming limit diagrams (FLDs). ...

Abstract: A scratch intersection based material removal mechanism for CMP processes is proposed in this paper. The experimentally observed deformation pattern by SEM and the trends of the measured force ...
