A shear test is an important procedure that helps to ensure safety in the use of various manufacturing and industrial processes. 

If you need to shear test materials for your operation, you should be aware of the following five things:

Shear testing involves applying pressure to a test material to see what type of force is necessary to cause it to fail when parallel forces are applied to it.

A shear test determines the sliding failure that a material will exhibit when forces are applied in a parallel direction.

A shear force is typically understand to be two surfaces of a particular material moving in opposite directions against one another. It involves testing the sliding motion of two surfaces of a material against one another.

A shear test is distinct from a compression and tension test.

Compression and tension tests are two other types of test used to test the strength of materials. However, they are distinct from shear tests.

A compression test is a test that involves examining how well a material resists forces applied from above that push the material into itself. It tests how compressive forces reduce the size of the material sample.

A tension test tests how a material responds to forces pulling in opposite directions and stretching out the material sample. 

Shear tests are important for analyzing the design capabilities of fasteners like screws and bolts.

One of the most common reasons why a shear test needs to be performed is to determine the strength of certain types of fastener. Shear strength is an important quality in fasteners like screws, bolts, and adhesives because they typically work when two materials are forced against one another in different directions. 

There are two commonly used types of shear test.

The most commonly used shear test options out there are bend fixture tests or tests that involve tapered ends fixated to grips. 

There are three types of material that are generally analyzed with a shear test.

The types of materials that are typically tested through a shear test to determine performance are adhesives, layered composites, and rigid substrates.

Adhesives bond two materials together and can be made from a wide variety of materials. A layered substrate works much like an adhesive and experiences shear stress when shear forces are applied to a substance holding them together such as a laminate or glue. Rigid substrates are typically made up of metal, plastic, ceramic, wood, or composite materials.
