The Analysis for a creep behaviour of SMA Nitinol wire is presented along with material used is Nitinol alloy for increasing temperature tensile tests for constant load. The main characteristics, which appears in SMA, are the effect of shape memory and super elastic propertyy. This paper discusses about the behaviour of SMA Nitinol wire and its properties shown in tensile testing machine. In this analysis, we have used the parameter like strain, temperature, time; load to obtain the required result and plot the graph. Due to distinct properties of nitinol, it has variety of application in automobile, heat engine, etc. While performing loading under consistent rate of pressure per unit area temperature increments because of stress actuated in martensitic change. The deformation properties are vital because the deviation of SMA elements can change under consistent stress in the model of SMA element.
