Plastic Deformations in Complex Plasmas
Physical Review Letters, 2011Complex plasmas are macroscopic model systems of real solids and liquids, used to study underdamped dynamics and wave phenomena. Plastic deformations of complex plasma crystals under slow uniaxial compression have been studied experimentally and numerically.

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

This chapter presents the production of light alloys (Ti-Mg) by severe plastic deformation. Alloys with different Mg content were synthesized by high-pressure torsion straining, technique that allows to obtain ultrafine-grained materials in both equilibrium and nonequilibrium, changing the chemical, thermodynamic, and mechanical properties of the ...

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 ...

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.

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 ...
