Current Situation and Prospect of Elastic Modulus Test of Insulating Materials
Elastic modulus is an indicator of a material's ability to resist elastic deformation and an important mechanical property parameter of insulating materials. This paper provides an overview of the commonly used methods for measuring the elastic modulus of insulating materials, and elaborates on strain detection techniques such as equipment displacement method, digital display meter method, extensometer or deflection meter method, and photoelectric tracking method. The future development of elastic modulus testing technology of insulating materials is prospected, and the elastic modulus testing methods of other types of materials are introduced: dynamic resonance method, wave propagation method, model calculation method.
