Abstract: The workability of aluminum alloy 7075-T6 was investigated in upsetting and rolling at room temperature with reference to occurrence of free-surface cracks. The fracture criterion was established ...

Abstract: In the present investigation, an FEM code SHPROL has been developed for three-dimensional simulations of shape rolling processes. SHPROL is capable of handling arbitrary roll profiles and follows ...

Abstract: Two types of sheet forming processes are analyzed by rigid-viscoplastic FEM (Finite Element Method): axisymmetric punch stretching and hydrostatic bulge forming. The present formulations, based on ...

Abstract: The present investigation is concerned with the application of theories on flow and fracture to the prediction of workability of materials in axisymmetric bar extrusion and drawing, with special ...

Abstract: In this part of the present investigation, the validity of the theory on ductile fracture was examined by the experimental data found in the literature. Then, combining the formulation of ...

Abstract: The isothermal forging of a titanium alloy engine disk is analyzed by the rigid-viscoplastic finite element method. Deformation mechanics of the forging process are discussed, based on the ...
