Rate Independent Hysteresis

2000
We outline some basic features of the mathematical theory of hysteresis operators and indicate connections to applications, in particular magnetics and mechanics.

Analysis of evolution: Evolutionary rates, independence and treeness

Theoretical Population Biology, 1975
Abstract Populations that separate according to a given pattern of fissions (a “tree” of descent) and evolve independently after fissions have a patterned variance—covariance matrix which reflects the history of fissions. Spectral analysis of the matrix can help reconstruct the pattern; multivariate analysis techniques can be used to test if an ...

Is centenarian rate independent from economy?

Archives of Gerontology and Geriatrics, 2021
Economy development and income are compactly associated with mortality of infant, children, young people, and mid age all over the world, and high income brings higher life expectancy, aging rate and 80+ rate as a result. On the contrary, the relationship between income and centenarian rate is obscure, in China, low income regions have lower life ...

Constitutive modelling for rate-independent soils: a review

Revue Française de Génie Civil, 2002
The paper presents a review of some of the most widely used constitutive theories for rate-independent geomaterials, including non-linear elasticity, classical and generalized elastoplasticity and hypoplasticity. In the discussion of the different approaches, the incremental nature of the constitutive equation is adopted as a principal classification ...

Computational Isotropic-Workhardening Rate-Independent Elastoplasticity

Journal of Applied Mechanics, 2003
A novel formulation for elastoplasticity has been recently proposed by Liu and Hong. These authors have explored the internal symmetry of the constitutive model for perfect plasticity to ensure that the consistency condition is satisfied at each time step.

The Dissipation‐Inequality of Rate‐Independent Thermoplasticity

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1999
AbstractIn real processes involving large plastic deformations a major part of the stress power will be dissipated and involves thermodynamical changes that cannot be neglected. A framework for the description of thermoplastic processes based on the notion of isomorphic thermoelastic ranges is suggested.

Rate-independent systems in Banach spaces

2015
In the Banach-space setting, we assume that the topologies are given by either the weak or the strong topology. Throughout this chapter, we will assume that the topological spaces \(\mathcal{Y}\) and \(\mathcal{Z}\) of Chapter 2 are given via separable reflexive Banach spaces \(\boldsymbol{Y }\) and \(\boldsymbol{Z}\) equipped with their weak ...

Sweeping processes and rate independence

2016
Let \(\mathcal{H}\) be a Banach space; \(\mathcal{C}(t),\) \(t \geq 0\), a nonempty closed comvex subset of \(\mathcal{H}\). The following sweeping process is considered: under the assumption that \(t \multimap \mathcal{C}(t)\) is a right continuous, locally bounded variation multifunction with respect to the Hausdorff distance one has to find a right ...
