Nonuniqueness in Contained Plastic Deformation

Journal of Applied Mechanics, 1980
It is well known that in a well-defined load-controlled boundary-value problem for an elastic/perfectly-plastic structure the displacements are unique if the structure is everywhere elastic, and they are not unique at the yield-point load when the structure becomes a mechanism.

Plastic Deformations in Complex Plasmas

Physical Review Letters, 2011
Complex 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.

Plastic Deformation of CuAl₂

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, 1999
We 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, 1992
It 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 ...

Crystalline Plasticity and Structured Deformations

2004
The 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 ...
