Abstract

Most thermal shape memory alloy valve concepts are based on shape memory alloy spring actuators. Because the development of these elements itself is complex, a methodical approach is focused in this chapter by a calculation method of these actuators. A special attention is laid in this chapter on the backgrounds of the calculations and the possible parameters which can be set during the spring element development.
