The shape memory alloy controlled by the sun’s radiation effect

摘要

The Shape Memory Alloys (SMAs) are smart materials, which have many thermo-mechanical characteristics that can back to their initial strain when they exposed to a definite temperature. They are materials that change their mechanical proprieties in response to stress or heating such as shape, displa cement and frequency, which are useful for actuators in many domains such as industry, robotics and engineering. In order to realize thermo-mechanical investigation about Shape Memory Alloy Actuator (SMAA) controlled by the radiation effect, which is useful for renewable energy applications. In this way, numerical simulation simulates shape memory alloy at different temperatures, to show the ability of this materials in various conditions and the parameters are obtained by previous experimental measurements. The first results are pleasing.
