How the Direct Shear Test is conducted?

In the previous tutorial, we have discussed the list of Material Testing Methods, and in this tutorial, we are going to discuss how to conduct the Direct Shear Test.

Direct Shear Test

The shear test is conducted to measure the shear strength of the material. Shear strength test comes under the destructive test where we apply the gradually increased load up to the material get a fracture. So the Shear strength test also a static test as sub-classification.

• The direct shearing test will be conducted in two tests. One is Singel shear test and the second one is the Double shear test.
• In the shear testing, rectangular cross-section will be used as the specimen.
• In the single shear test, one side of the specimen will be clamped and the other side will be subjected to verticle load.
• In double shear test both sides of the specimen will be clamped and at the middle portion, the vertical load will be subjected.

  

• The clearance is shown on the diagram represents the shearing portion in the specimen.
• The Shear Strength of the specimen will be calculated as the amount of the force needed to make the shear over the given cross-sectional area.
• Shear strength = Applied Load/Area in Shear

Conclusion

This is how we will conduct the Direct Shear test and observation of the fracture for the different materials. If you have any thought please let us know in the comments sections.
