In-situ testing equipment for testing micromechanical properties of material in multi-load and multi-physical field coupled condition

Abstract

An in-situ testing equipment for testing micromechanical properties of a material in a multi-load and multi-physical field coupled condition is disclosed. The equipment comprises a frame supporting module, a tension/compression-low cycle fatigue module, a torsioning module (), a three-point bending module (), an impressing module (), a thermal field and magnetic field application module (), an in-situ observation module () and a clamp body module (). The testing equipment is capable of realizing applications of five different types of loads including tension/compression, low cycle fatigue, torsion, bending and impressing, performing an intensive study on micromechanical properties of the material in the multi-load and multi-physical field coupled condition by using built-in electric, thermal and magnetic application modules and the in-situ observation module, and acquiring relations between deformation behavior, mechanism of damage, performance weakening of the material, applied loads and material properties.
