“…Apart from the many numerical modeling attempts , several laboratories, sometimes independently each from the other and sometimes in strict connection, investigated experimentally the hysteresis offered by the different alloys. In Bochum, Germany, the existing SMA center is engaged in an effort to explain the elementary processes that determine the structural and functional fatigue of SMA .…”

The fatigue performance of shape memory alloys is one of the main features to assess their potential in most applications (i.e., in vibration mitigation). As experimental results showed, the hysteretic properties of shape memory alloys highly depend on chemical composition, manufacturing process, and loading strain rate. In this paper, commercial wires of Nickel-Titanium (of diameter 0.2 mm) are investigated. Specimens of different length are tested under cycles of loading-unloading either on a shaking table or on an MTS Systems Corporation hydraulic testing apparatus (MiniBionix II). The fatigue results of the research campaign are then synthesized in an interpolating model.

“…Given the force increment 'P we obtained the increment of the maximum stress 'ߪ ௫ ( ) for i-th beam in the cascade. Then using the microstructural model [25,26] Determine the macroscopic stress as 6 = ෨ ௌ(ଵି ) మ , where ܲ ෨ is the force applied to the whole sample, S is the cross-section area of the sample, p is the porosity measured by the random secant method. Then the relation between the local force P applied to the cascade and the macroscopic stress 6 can be written as 6 = ෨ ෩ (ଵି ) .…”

“…In the present work we used an earlier developed microstructural model for calculation of the phase deformation of an SMA [25][26][27]. In these works it was shown that this model allowed describing such functional properties of SMA as pseudoelasticity, pseudoplasticity (ferroelastisity), transformation plasticity and shape memory effect.…”

Abstract.A model accounting for the microstructure of porous TiNi shape memory alloy samples fabricated by selfpropagating high temperature synthesis has been proposed for simulation of their functional-mechanical properties. Structural elements of a porous sample have been approximated by curved beams. An analysis of shapes and sizes of pores and ligaments permitted to identify characteristic sizes of the beams. A mathematical object consisting of rigidly connected small curve beams has been considered. The stress-strain state of a beam was estimated by the classical methods of strength of materials. The microstructural model was used for calculation of the phase deformation of the shape memory material. Simulation of stress-strain curves and phase deformation of a porous TiNi sample on cooling and heating under a constant stress has shown a good correspondence between the experimental data and the results of modeling.

“…In turn, these devices also need to be controlled [Ashrafiuon and Elahinia, 2015;Benafan et al, 2014]. SMA elements can also be used to control of various processes [Volkov et al, 2014;Torra et al, 2015]. One of the promising devices types are SMA holding and release devices for space applications [Razov and Cherniavsky, 2003;Hartl and Lagoudas, 2007;Rongqiang et al, 2016].…”

Functional properties of conical working elements of the holding and release device for space application needed to control the device were investigated. The elements had 45 mm in diameter, 11 mm in height and 2 mm in thickness, and were made of TiNi shape memory alloy with characteristic temperatures of marten-Constraint forces and displacement recovery of the conical working elements as functions of the temperature were received. It was found that the friction loss for two conical elements put one in the other one reach 15%. A simple graphical method to evaluate the displacement recovery and constraint forces of such conical working elements needed to control the device is proposed.
