A system for in-situ testing of mechanical properties of materials in static and dynamic load spectra, that includes: an Arcan biaxial clamping subsystem, a press-in test subsystem, a biaxial fatigue test subsystem, a biaxial pre-tension loading subsystem, a signal detection subsystem, and a support and adjustment subsystem. A combined guide mechanism in the Arcan biaxial clamping subsystem is rigidly connected to a guide mechanism support block, an x-direction three sensor base and a y-direction force sensor base in the support and adjustment subsystem by threaded connections, respectively. A laser transmitter, a voice coil motor and a laser receiver in the press-in test subsystem are rigidly connected to a two-degree-of-freedom electric moving platform for the laser transmitter, a two-degree-of-freedom electric moving platform for the voice coil motor and a two-degree-of-freedom electric moving platform for the laser receiver in the support and adjustment subsystem by threaded connections, respectively.

System and method for in-situ testing of mechanical properties of materials in static and dynamic load spectra

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.
