Abstract: The matrix method for the analysis of rigid-plastic deformation problems was described and applied to simple compression of cylinders and plane-stress bore expanding and flange drawing. In cylinder ...

Abstract: An upper-bound velocity field that considers bulging has been applied to cylinder and ring upsetting. Computer programs have been developed to (a) determine strain, strain rate, velocity, and ...

Abstract: Detailed studies of the deformation characteristics in axisymmetric upsetting and plane-strain side-pressing were attempted by the finite element method. Solutions were obtained up to a 33 percent ...

Abstract: The behavior of impacting systems is highly nonlinear and generally numerical analysis must be resorted to if a quantitative description of the behavior of such systems is required. However, ...

Abstract: Boundary-element methods, also known as panel methods, have been widely used for computations of wave loads and other hydrodynamic characteristics associated with the interactions of offshore ...

Abstract: Three problems, namely, autofrettage process, plastic upsetting of a solid cylinder, and plane-strain and axisymmetric extrusion, are treated for residual stress calculation. A thick-walled cylinder ...

Abstract: In this study, the use of organically modified clay to remove the high-strength organic pollutants in leachate as well as reduce its liquid flow was investigated. Various physical and chemical factors that may affect the ...
