Plastic Deformation Behavior under Conditions of Combined Stressristics for both isotropic and anisotropic materials are discussed, and the rules for anisotropy induced by prestrain and for work-hardening caused by subsequent strain are determined. An equation which represents the yield surfaces for large subsequent strain of prestrained materials is proposed.

Sheet Necking-III. Strain-Rate Effectso substantially increase the predicted limit strains beyond their corresponding values for time-independent material response. We also discuss the influence of strain-rate dependence on imperfection- sensitivity and forming limit curves.

Plastic Deformation Behavior under Conditions of Combined Stressepresent the results systematically, a yield surface in the σ., σ.,σ., 3τ., stress space for large plastic strain is used. The work-hardening characteristics for both isotropic and anisotropic materials are discussed, and the rules for anisotropy induced by prestrain and for work-hardening caused by

Sheet Necking—I. Validity of Plane Stress Assumptions of the Long-Wavelength Approximation an exact solution for the growth-rate of a small amplitude, sinusoidal thickness variation in a sheet of material characterized by . = ασ. in simple tension. The plane stress assumptions become accurate when the ratio of variation wavelength to average thickness exceeds four and otherwise lead to o
