Hysteresis in Magnetic Shape Memory Composites: Modeling and Simulation
Magnetic shape memory alloys are characterized by the coupling between a structural phase transition and magnetic one. This permits to control the shape change via an external magnetic field, at least in single crystals. Composite materials with single-crystalline particles embedded in a softer matrix have been proposed as a way to overcome the blocking of the transformation at grain boundaries...
متن کاملModeling and Simulation of Magnetic Shape--Memory Polymer Composites
Composites of small magnetic-shape-memory (MSM) particles embedded in a polymer matrix have been proposed as an energy damping mechanism and as actuators. Compared to a single crystal bulk material, the production is simpler and more flexible, as both type of the polymer and geometry of the microstructure can be tuned. Compared to polycrystals, in composites the soft polymer matrix permits the ...
متن کاملModeling and Simulation of Large Microstructured Particles in Magnetic-Shape-Memory Composites
Magnetic shape memory (MSM) materials are characterized by two coupled phase transitions, in which a ferromagnetic order parameter (the magnetization) and a ferroelastic one (the elastic strain) interact with each other. The coupling leads to very large spontaneous strains, of the order of 10%, but also generates strong impediments to the transformation, including in particular the di culty of ...
متن کاملHysteresis Modeling of Magnetic Shape Memory Alloy Actuator Based on Krasnosel'skii-Pokrovskii Model
As a new type of intelligent material, magnetically shape memory alloy (MSMA) has a good performance in its applications in the actuator manufacturing. Compared with traditional actuators, MSMA actuator has the advantages as fast response and large deformation; however, the hysteresis nonlinearity of the MSMA actuator restricts its further improving of control precision. In this paper, an impro...
متن کاملShape-Memory Polymer Composites
The development of shape-memory polymer composites (SMPCs) enables high recovery stress levels as well as novel functions such as electrical conductivity, magnetism, and biofunctionality. In this review chapter the substantial enhancement in mechanical properties of shape-memory polymers (SMPs) by incorporating small amounts of stiff fillers will be highlighted exemplarily for clay and polyhedr...
