Plate shear test device

Abstract

The invention discloses a plate shear test device, which comprises a base, a fixed splint, a sliding splint and a slide rail. The base can be connected to the workbench of the testing machine, and thesliding splint is connected with a slider that is slideably arranged on the slide rail. The fixed splint and the sliding splint can clamp both ends of the plate to be tested, and there is a gap between the plate to be tested and the base. During the test, the base can be fixed on the workbench of a universal testing machine or a pressure testing machine, the fixed splint and the sliding splint are respectively fixed at both ends of the plate to be tested, then a load is applied to the plate to be tested, a shearing effect is produced on the plate to be tested when the the slider moves down the slide, the deformation of the test piece is observed and the photo record is taken. The plate shear test device of the invention can be fixed on the testing machine, and the in-plane shear test of the plate is performed within the load range allowed by the test machine, so as to obtain accurate and reliable results, convenient operation, low test difficulty and high test efficiency.

Description

technical field [0001] The invention relates to the technical field of plate shear tests, in particular to a plate shear test device. Background technique [0002] Plate members are often subjected to shear force during work, and the plate produces shear deformation at this time. Therefore, it is of great significance to understand the mechanical properties of the plate under the action of shear force for engineering design and application. Universal testing machine is one of the testing instruments for tensile, compression, bending and shearing tests of various material samples. It is widely used in various departments such as universities, scientific research units, quality inspection departments, etc. The test for measuring the shear resistance of the plate cannot be carried out on the press, and there is no special testing machine for the shear test in the prior art, which undoubtedly increases the difficulty of carrying out the shear test of the plate.
