Introduction to the direct shear test

The direct shear test is one of the material mechanics testing methods. It is used to determine the shear strength and shear stiffness of the material. It can also be used to study the shear behavior of the material. Strain and failure morphology under loading. Direct shear test is a common experimental method widely used in geotechnical, rock, concrete and metal fields.

In direct shear tests, the commonly used specimens are rectangular or square standard specimens, and the shear loading of the material is achieved through incisions. Shear force is applied during the test, and the shear resistance of the material is recorded and analyzed. Through direct shear tests, parameters such as shear strength and shear modulus of the material can be obtained, thereby gaining a deeper understanding of the mechanical properties of the material.

The equipment for direct shear testing mainly includes direct shear testing machines. Torque measuring devices and displacement measuring devices are usually installed to measure the shear force and displacement of the material during the loading process, so as to obtain the shear strength and shear strength. Cutting modulus and other parameters.

What are BAIJIAN material testing laboratories? Advantages?

1. Collectively owned testing institution with complete qualifications and scientific, fair and accurate test reports.

2. Multiple laboratory branches are located across the country, supporting door-to-door sampling/sending samples for testing.

3. The testing cycle is short, the testing cost is low, and the experimental plan is more complete.

4. For initial inspection of samples, no testing fees will be charged during the initial inspection.

5. The test report supports scanning the QR code to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to the direct shear test. If you have other needs, you can consult the laboratory engineer to help you solve it.
