Hysteresis in column systems

Numerical Investigation of Semi-rigid Column Bases with Hysteresis Characteristics

Original scientific paper The results of numerical experiments on dynamic response of a steel column, with a concentrated mass on the top are presented. The column is fixed in the base subjected to a triangular pulse force. Preisach hysteresis model was applied to investigate the dynamic behaviour of the steel column. In the solution of the non-linear dynamic equation of the motion the fix-poin...

AdiAbAtic dynAmicAl SyStemS And HyStereSiS

This work is dedicated to the study of Dynamical Systems depending on a slowly vary ing parameter It contains in particular a detailed analysis of memory e ects such as hysteresis which frequently appear in systems involving several time scales In a rst part of this dissertation we develop a mathematical framework to deal with adiabatic di erential equations We do this whenever possible by favo...

Hysteresis in one-dimensional reaction-diffusion systems.

We introduce a simple nonequilibrium model for a driven diffusive system with nonconservative reaction kinetics in one dimension. The steady state exhibits a phase with broken ergodicity and hysteresis which has no analog in systems investigated previously. We identify the main dynamical mode, viz., the random motion of a shock in an effective potential, which provides a unified framework for u...

Scaling on hysteresis dispersion in ferroelectric systems

The hysteresis area as a function of frequency of the time-varying external electric field—hysteresis dispersion—for ferroelectric Pb~Zr0.52Ti0.48!O3 is measured, and the Monte-Carlo simulation on the hysteresis dispersion for a model ferroelectric lattice is performed too. We demonstrate the scaling behavior of the single-peaked hysteresis dispersion for the two ferroelectric systems, predicti...
