چکیده
The evolution of an elastic-plastic material is modeled as an initial boundary value problem consisting of the dynamic momentum equation coupled with a constitutive law for which the hysteretic dependence between stress and strain is described by a system of variational inequalities. This system is posed as an evolution equation in Hilbert space for which is proved the existence and uniqueness of three classes of solutions which are distinguished by their regularity.

The Effect of Axial Force Variations on Nonlinear Modeling and Seismic Response of Reinforced Concrete Structures
In order to increase the accuracy of evaluating seismic response of structures, it is critical to conduct dynamic analyses based upon precise nonlinear models being as consistent as possible with the real conditions of corresponding structures. The concentrated plasticity model including one elastic element and two nonlinear spring elements at both ends has been considered within the research c...
متن کاملDAMAGE AND PLASTICITY CONSTANTS OF CONVENTIONAL AND HIGH-STRENGTH CONCRETE PART II: STATISTICAL EQUATION DEVELOPMENT USING GENETIC PROGRAMMING
Several researchers have proved that the constitutive models of concrete based on combination of continuum damage and plasticity theories are able to reproduce the major aspects of concrete behavior. A problem of such damage-plasticity models is associated with the material constants which are needed to be determined before using the model. These constants are in fact the connectors of constitu...
متن کاملDynamic Analysis of Porous Media using Generalized Plasticity Model and Non-Darcy Flow Rule
Biot equations that consider fluid and soil interaction at the same time are the most applicable relationships in the soil dynamic analysis. However, in dynamic analysis, due to the sudden increase in the excess pore pressure caused by seismic excitation and the occurrence of high hydraulic gradients, the assumption of the Darcy flow used in these equations is questionable. In the present study...
متن کاملHuman Neural Plasticity
Neuroscience research in slice preparations and animal models within the last decade has shown that neural plasticity is a ubiquitous mechanism by which the brain represents and encodes its dynamic sensory world. This workshop considered how dynamic sensory representations are modified by experience, new methods for imaging those representations in human subjects, and applications of human neur...
متن کاملMechanisms of Induction and Maintenance of Spike-Timing Dependent Plasticity in Biophysical Synapse Models
We review biophysical models of synaptic plasticity, with a focus on spike-timing dependent plasticity (STDP). The common property of the discussed models is that synaptic changes depend on the dynamics of the intracellular calcium concentration, which itself depends on pre- and postsynaptic activity. We start by discussing simple models in which plasticity changes are based directly on calcium...
متن کاملA Strain Range Dependent Cyclic Plasticity Model
Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...
