What is a compression shear testing machine?
In the field of engineering materials and construction, the compression shear testing machine is an important testing equipment used to evaluate the performance of materials under compression and shear forces. This article will introduce in detail the definition, working principle, application fields and recent hot topics of the compression shear testing machine.
1. Definition of compression shear testing machine
The compression shear testing machine is a device used to test the mechanical properties of materials under combined compression and shear loads. By applying vertical pressure and horizontal shear forces, it simulates the multi-directional stress conditions that a material may encounter in actual use to evaluate its strength, stiffness and durability.
2. Working principle of compression shear testing machine
Compression shear testing machines usually consist of the following parts:
| components | Function |
|---|---|
| Load system | Apply vertical pressure and horizontal shear forces |
| control system | Adjust loading speed and force |
| Measurement system | Record material deformation and stress data |
| fixture | Fix the specimen and transfer the load |
During the test, the specimen is fixed in the fixture, the loading system applies vertical pressure and horizontal shear force, the measurement system records data in real time, and finally generates stress-strain curves and other mechanical parameters.
