An Experimental and Theoretical Study of the Parabolic Generalization for the Plastic Deformation of Metals.

Abstract

The results of several years of research are briefly described and shown to provide a solid experimental foundation for the subject of crystal plasticity. A unifying generalization has been established in the form of a linearly temperature dependent parabolic stress-strain function which is applicable to the finite deformation of many crystalline solids. The interrelation of this generalization with many topics of crystal plasticity is discussed. These topics include: the double slip deformation hypothesis for face-centered cubic single crystals; the polycrystalline aggregate theory; plane wave, incompressible dynamic plasticity; the finite deformation mode and transition structure; the quantized structure of zero point isotropic shear moduli; the Portevin - Le Chatelier effect; deformation of binary alloys; combined tension-torsion stress states; tensile plastic waves and dynamic plasticity at elevated temperatures.
