dc.description.abstractThe flow stress of a common shape memory alloy, a particular alloy of nitinol is investigated and presented as a function of temperature and strain. The reversion stress, that stress necessary to maintain a constant strain as a result of a martensitic phase transforming to the parent phase, is presented as a function of temperature and amount of pre-strain. This reversion stress is demonstrated to approximate, during the cooling process, the flow stress. The stability of the reversion stress is investigated and is presented as a function of time at 220 C. A model of a shipboard device utilizing a shape memory alloy is constructed and studied to compare with pure tensile data.
