In the present paper, nonlinear dynamic analysis of low-velocity impact of rectangular composite plates reinforced by SMA strips is investigated. In this regard, effects of the instant phase changes and the local and istatantaneous non-uniform distribution of transformation of the austenite to martensite phases and vice versa is considered, for the first time, implementing a written user define...

Performance-based optimization of energy dissipation devices in structures necessitates massive and repetitive dynamic analyses. In the endurance time method known as a rather fast analysis procedure, are subjected to intensifying excitations their response at multiple intensity levels is estimated by minimal number So, this significantly reduces computational endeavors. paper, employed determi...

In order to investigate the structural performance of CLT-S hybrid structure with several types connections improve hysteresis behavior, experiments frame were conducted. new connections, reduced section parts inserted steel plate restrained for buckling provide improved behavior against cyclic axial forces due bending moment in CLT panels. From experiment result, it was found that hysteretic p...

Experimental studies were conducted by some researchers to investigate the cyclic performance of CFSretrofitted columns; however there is a need to develop analytical methods which can simulate its hysteretic response. This study presents an analysis of the hysteretic behavior of CFS-retrofitted reinforced concrete circular columns. Fiber element analysis was conducted based on cyclic constitut...

Experiments in drums or cylinders partly filled with a granular system and rotated constantly about their horizontally aligned axis of symmetry show a hysteretic transition from discrete avalanches to continuous flow if the rotation rate is adiabatically changed. Herein, we show that this hysteresis can be explained by the impact of global Langevin-type fluctuations in a recently proposed minim...

We show that the coupling of simple dynamical systems with a typical model for hysteresis, the Preisach model, leads to interesting new scenarios in nonlinear dynamics. The Preisach model is known from many branches of science to be a universal model for complex, non-local hysteresis. We provide results for three cases, for two, where the Preisach model simply acts as hysteretic transducer for ...

The Derjaguin-Broekhoff-de Boer theory of capillary condensation is employed to describe deformation of mesoporous solids in the course of adsorption-desorption hysteretic cycles. We suggest a thermodynamic model, which relates the mechanical stress induced by the adsorbed phase to the adsorption isotherm. Analytical expressions are derived for the dependence of the solvation pressure on the va...

The recently proposed hysteretic optimization (HO) procedure is applied to the 1D Ising spin chain with long range interactions. To study its effectiveness, the quality of ground state energies found as a function of the distance dependence exponent, σ, is assessed. It is found that the transition from an infinite range to a long range interaction at σ = 0.5 is accompanied by a sharp decrease i...

In recent years, thin-walled accordion tubes under axial cyclic loading due to their appropriate energy absorption mechanism and behavioral characteristics were suggested as hysteretic metallic dampers. The effectiveness of accordion metallic damper (AMD) to protect and mitigate the response of structures under seismic loading is well established both experimentally and analytically. In this pa...
