RISAn Interpretation of Slip-Line Field Patterns in Plane Plastic Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of interpretation of slip-line field solutions is proposed. Contour maps showing lines joining points of equal vertical or horizontal displacement velocity are plotted superimposed on ...
Estimation of Dynamic Forces in Very High-Speed Impact Forging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study is made of three methods of estimating die loads in impact forging: By approximate solution of the equations of equilibrium; by an energy method, assuming plane sections remain plane; ...
Stability of the Hinge Formed in an Ideal Rigid-Plastic Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hinge formed at yield in an ideal rigid-plastic beam is considered plastically stable if the moment of resistance increases after a small deformation, and unstable if the moment decreases. ...
The Mechanics of Some New Processes of Cup Drawing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An attempt is made to indicate and explain some advantages of processes of cup drawing of metals which use a superposed fluid pressure. The mechanics of tensile necking failure is used to ...

Instability Strains in Plane Sheet Under Biaxial Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress ratios, loads, and plastic strains at instability are calculated for a flat metal sheet subjected to the following loading paths: (a) Proportional stressing, (b) sequential loading, ...
Yield, Flow and Tensile Plastic Instability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of choice of yield criterion and flow rule on tensile plastic instability is discussed. It is shown that under certain circumstances this choice can lead to widely different values ...
