Shape memory alloys hysteresis
Webb12 juli 2024 · Hysteresis Modeling and Analysis of Magnetic Shape Memory Alloy-Driven Actuator. Abstract: The accuracy of the micro-positioning system impelled by a magnetic shape memory alloy-driven actuator (MSMADA), is severely restricted by the frequency-dependent hysteresis nonlinearity. WebbIn this paper, the superelasticity effects of architected shape memory alloys (SMAs) are focused on by using a multiscale approach. Firstly, a parametric analysis at the cellular level with a series of representative volume elements (RVEs) is carried out to predict the relations between the void fraction, the total stiffness, the hysteresis effect and the …
