Abstract

The minor deformation in a material is an important factor which influences the failure of component. Monitoring the deformation accurately is the basis for rationally evaluating the residual life of components. However, the existing technical means remain limited by complex environment. In this work, a method for evaluating material strain is established based on potential drop technology, and the accurate prediction of experimental results is conducted by the finite element technique. Both results are in accordance with the theoretical mathematical model. Through the experiment carried out on 304 stainless steel tensile specimens, the relationship between potential drop and strain based on this method is established. The experimental results basically comply with the finite element results and the theoretical derivation.
