    Abstract

    An improved procedure for theoretically determining the apparent strain is proposed. Based on the results of an experimental study into the behaviour of high temperature strain gages in a varying thermal environment a theoretical formula is developed. One of the significant features of the proposed formula lies in its ability to predict the apparent strain without actually carrying out the experiment, provided the relevant strain gage material parameters as also the coefficient of thermal expansion of the specimen material are known. A comparison study of the results obtained by using the proposed formula with the experimentally determined results shows excellent agreement. Its application to the development of improved temperature compensated gages is also indicated.
