AI Technical Summary
Traditional uniaxial tensile testing cannot simulate the real service conditions of materials under multiaxial stress states. Existing biaxial testing machines have problems such as large size, difficulty in controlling synchronous load/displacement loading, and low accuracy.
A quasi-static in-situ biaxial tensile mechanical property testing device was designed, including a support platform, a transmission component, a variable slope cam transmission component, a linear guide component, a force sensor component, and a clamping component. The tensile speed of the X and Y axes is adjusted by the variable slope cam transmission component to achieve precise variable speed synchronous loading of the biaxial specimen.
This technology enables the study of the yielding behavior of materials under biaxial stress, allowing for in-situ observations using scanning electron microscopy, X-ray imaging, and other methods, thus improving the accuracy and precision of research on the micromechanical properties of materials.
