Hysteresis is a nonlinear phenomenon exhibited by systems stemming from various science and engineering areas. To detect experimentally the presence of hysteresis in a system, the graph output versus input of the system is plotted for different frequencies of the input. For hysteresis systems, these graphs converge to a quasi-static limit set when the frequency goes to zero. Moreover, the quasi...

A study is made of the propagation of time-harmonic magneto-thermoviscoelastic plane waves in a homogeneous electrically conducting viscoelastic medium of Kelvin-Voigt type permeated by a primary uniform external magnetic field when the entire medium rotates with a uniform angular velocity. The generalized thermoelasticity theory of type II (Green and Naghdi model) is used to study the propagat...

We review the classical theory of static and quasi-static plasticity in an abstract framework of convex analysis. It can be shown that the extended use of orthogonal projections onto closed convex sets simplifies the analysis substantially. We present new characterizations of the primal problem in plasticity. The abstract setting is applied to problems in perfect plasticity and to plasticity wi...

To solve the problem of resonance during quasi-static calibration of high-g accelerometers, we deduce the relationship between the minimum excitation pulse width and the resonant frequency of the calibrated accelerometer according to the second-order mathematical model of the accelerometer, and improve the quasi-static calibration theory. We establish a quasi-static calibration testing system, ...
