Structure Calculations Applied to Shape Memory Alloys
Despite the potential of these alloys and the amount of patents, successful industrial and commercial applications of Shape Memory Alloys (SMA) remain exceptions. This can be explained by the lack of design tools able to dimension correctly SMA elements because the non elastic behavior of SMA lead the classical method of design to be inefficient. Furthermore, this behavior is strongly dependent...
متن کاملnumerical analysis of thermo-mechanical coupling in shape memory alloys
the phase transformation phenomenon due to the crystallographic change of shape memory alloys subjected to mechanical or thermal loading is very complicated. regarding the thermo-mechanical coupling effects in shape memory alloys, in case of high loading rates, heat generation/absorption during the forward/reverse transformation, will lead in temperature-dependent variation and consequently af...
متن کاملApplication of Shape Memory Alloys in Seismic Isolation: A Review
In the last two decades, there has been an increasing interest in structural engineering control methods. Shape memory alloys and seismic isolation systems are examples of passive control systems that use of any one alone, effectively improve the seismic performance of the structure. Characteristics such as large strain range without any residual deformation, high damping capacity, excellent re...
متن کاملShape Memory Alloys
THE TERM SHAPE MEMORY ALLOYS (SMA) is applied to that group of metallic materials that demonstrate the ability to return to some previously defined shape or size when subjected to the appropriate thermal procedure. Generally, these materials can be plastically deformed at some relatively low temperature, and upon exposure to some higher temperature will return to their shape prior to the deform...

are compared with the experimental results. In these test results the shape memory alloys behavior as: super elasticity under various temperatures, loading rate effects, asymmetry in tension and pressure, various loops of loading and unloading, hydrostatic pressure effects, different proportional tension-shear biaxial loading and unloading, and also deviation from normality due to non-proportio...
