Physica Status Solidi (a), 1972
Properties of the intermetallic compound CuAl2 have been studied by compression and tension tests. Specimens fail by brittle fracture at ambient temperatures, but appreciable ductility is observed at homologous temperatures of about 0.8 Tm. The strain rate sensitivity and activation volume have been measured by stress relaxation; between 450 and 591°C ...

Seismic plastic deformation in the free-field
International Journal for Numerical and Analytical Methods in Geomechanics, 1999We present an analytical solution for free-field seismic elastoplastic deformations of granular dry soils. This solution is possible since the stress field solution from pseudostatic analysis is known at any acceleration level. We introduce a plastic potential function with two plastic material parameters to model the soil. This model can describe both

Dynamics of plastic deformation: Waves of localized plastic deformation in solids
Russian Physics Journal, 1992It has been shown here that a localized plastic deformation in structurally inhomogeneous media can be of a wave nature and can propagate in the form of nonlinear plastic waves, not only at the microscopic level but also at the mesoscopic level. It has been established that there is an interrelationship between this new effect and grain-boundary ...

Plastic deformation of polyethylene
Kolloid-Zeitschrift & Zeitschrift für Polymere, 1970The deformation behaviour during rolling is studied by small-angle X-ray scattering, density measurement, and investigation of the debris after fuming nitric acid treatment. Crystallinity and mechanical properties are compared with corresponding results on drawn material.

Deformation and strength in plastics
Physics in Technology, 1974Progress in the study of deformation and strength in plastics has been strongly bound to a scientific framework, although much technological advance has succeeded by regular excursions from this base. Deformation theories have passed through linear elasticity to linear viscoelasticity and at present dwell in nonlinear viscoelasticity, but many ...

Crystalline Plasticity and Structured Deformations
2004The connection between the geometrical changes at small length scales in single crystals and their macroscopic response has been the subject of extensive experimental studies. In (Deseri and Owen (2000)), experimental evidence that points to a connection between hardening behavior of single crystals undergoing single slip and changes in the separation ...

Fracture and Mesoscopic Plastic Deformation
2001This article discusses some recent advances in the understanding of plastic deformation near a crack tip at a mesoscopic scale. This is a scale that is in between the engineering macroscopic scale and the microscopic scale of the atomic description used by physicists.

Plastic Deformation Structures
2004AbstractMicrostructure and crystallographic texture are the key material features used in the continuous endeavor to relate the processing of a metal with its final properties. This article emphasizes several aspects of deformation microstructures, namely, microstructural evolution, dislocation boundaries, and macroscopic properties. It discusses three
