Clamp used for test piece sample in function material microscopic performance in-situ testing

Abstract

The invention relates to a clamp used for a test piece sample in function material microscopic performance in-situ testing, and belongs to the technical field of material microscopic performance testing and the technical field of mechanical and electronic integration. The clamp comprises clamp bodies, screwing sleeves, linings, pins, compacting wedge blocks, clamping wedge blocks, and other components. The screwing sleeves are connected to the clamp bodies and the compacting wedge blocks. The linings are in the clamp cavities and are connected to the internal circular surfaces of the clamp bodies. The linings are connected to the compacting wedge blocks and the clamping wedge blocks. The clamp is advantageous in that: clamping of the test piece sample in stretching tests, compression tests, torsion tests, and other single-load tests is achieved, clamping of the test piece sample in stretching-torsion tests, compression-torsion tests, stretching / compression-torsion tests, and other composite-load tests and corresponding fatigue loading tests is achieved; and the clamp is compatible with thermal field loading units, electric field loading units, magnetic field loading units, and other physical field loading units and therefore loading and testing of multiple physical fields and multiple loading modes for a test piece sample to be tested can be achieved. The clamp is compact in structure, convenient in operation and high in compatibility.

Description

technical field [0001] The invention relates to the technical field of material microscopic performance testing and the technical field of optical-mechanical-electrical integration, in particular to a fixture for specimen samples in in-situ testing of functional material microscopic performance. It can realize the clamping of specimen samples in the tensile / compression-torsion composite load test of functional materials, especially the pull-down / compression-torsion-bending multi-load material test pilot test in thermal, electrical, magnetic and other multi-physical field loading environments clamping of samples. Background technique [0002] In the last century, material testing machines were mainly aimed at structural materials. With the development of science and technology and economy, the large-scale application of new materials—especially ferro-electric, ferro-magnetic, thermal-magnetic and semiconductor materials, etc. The necessity of research on mechanical prope...
