Two lifting grooves are formed in the bottom of the detection groove, second hydraulic cylinders are mounted in the lifting grooves, a first hydraulic cylinder is mounted at the top of the mounting plate, a telescopic shaft of the first hydraulic cylinder penetrates through the mounting plate, a pressure sensor is arranged at the bottom of the connecting plate, and a pressing plate is fixedly connected to the bottom of the pressure sensor. The material strength detection device for the civil engineering mechanics experiment is provided with a first hydraulic cylinder, a pressure sensor and a second hydraulic cylinder, a telescopic shaft of the first hydraulic cylinder drives the pressure sensor and a pressing plate to integrally press downwards, the second hydraulic cylinder drives a material on a top plate to ascend, pressure is applied in two directions, and the material strength is detected. And the device can apply larger pressure to the material.
Description
technical field [0001] The invention relates to the technical field of material strength detection, in particular to a material strength detection device used in civil engineering mechanics experiments. Background technique [0002] The ability of a material to resist damage under the action of an external force is called the strength of the material. When the material is subjected to an external force, the internal stress will be generated, and the external force will increase, and the stress will increase accordingly until the bonding force between the internal particles of the material is not enough to resist the applied external force. , the material is destroyed, and the limit value reached by the stress when the material is destroyed is called the ultimate strength of the material, which is often expressed by f. The unit of material strength is MPa, and depending on the type of force, the strength of the material in different aspects may exist Differences, such as vert...
