Abstract: This paper conducts comparative study of elastic modulus measurement methods such as static method, single cantilever bending resonance method, suspended coupled bending resonance method and free beam bending resonance method, analyzes the related testing standards, and discusses the influence factors during the experiment. Of which, elastic modulus of three different samples are tested, the advantages and disadvantages of different experimental methods are compared, the development trends of elastic modulus at high temperature and in small-sized sample are discussed, and the applications of bending resonance methods in material research are considered. As results of resonance method have less dispersity and uncertainty than those of static method, it is suggested to consider the nondestructive testing method based on free beam bending resonance to measure material’s elastic modulus both at room temperature and high temperature.
