Perfect plasticity in a random medium
نویسندگان
چکیده
We study numerically a simple network model which is an electrical analog of a perfectly plastic disordered medium. For a uniform random distribution of local maximum current, (e.g. yield stress), we study the evolution of the properties of the system as a function of the number of elements which reached the plastic limit. It is shown that the macroscopic yield point can be interpreted as a critical point.

Cysteamine pretreatment reduces Mg2+-free medium-induced plasticity in the CA1 region of the rat hippocampal slices
Extracellular population responses are largely preferred for the study of long-term potentiation (LTP). The effect of Mg2+-free medium on changes in activity and plasticity of Schaffer collateral-CA1 pyramidal cell synapses was examined. Hippcampal slices from cysteamine-treated (200 mg/kg, s.c.) and saline-injected (1 ml/kg, s.c.) albino rats were perfused with ACSF. Population spikes (PS) wer...

متن کاملConstitutive Model for Multi-laminate Induced Anisotropic Double Hardening Elastic-plasticity of Sand
A constitutive multi-laminate based elastic-plastic model developed to be capable of accounting induced anisotropic behavior of granular material such as sand. The fabric feature or grain orientation characteristic effects through medium are considered in a rational way under any complex stress path, including cyclic loading. The salient feature of the developed model is a non-associative on pl...
متن کاملQuasi-static Evolutions in Linear Perfect Plasticity as a Variational Limit of Finite Plasticity: a One-dimensional Case
In the framework of the energetic approach to rate independent evolutions, we show that one-dimensional linear perfect plasticity can be obtained by linearization as a variational limit of a finite plasticity model with hardening proposed by A. Mielke (SIAM J. Math. Anal., 2004).
متن کاملHigh neuronal/astroglial differentiation plasticity of adult rat hippocampal neural stem/progenitor cells in response to the effects of embryonic and adult cerebrospinal fluids
Hippocampal neural stem/progenitor cells (hipp-NS/PCs) of the adult mammalian brain are important sources of neuronal and gial cell production. In this study, the main goal is to investigate the plasticity of these cells in neuronal/astroglial differentiations. To this end, the differentiation of the hipp-NS/PCs isolated from 3-month-old Wistar rats was investigated in response to the embryonic...
