- Shear is defined as the force that causes two contiguous parts of the same body to slide relative to each other in a direction parallel to their plane of contact.
- Shear strength is the stress required to yield or fracture the material in the plane of material cross-section.
- With current and evolving industry relying more heavily on composites and bonded materials, the need for reliable and accurate shear testing is at an all-time high.
- When parts or processes in a production are subjected to shear forces or stresses, quality control programs should include shear testing to ensure that processes are optimised and parts are safe.
- Fortunately, with the proper knowledge and test methods, shear testing can be performed accurately and reliably in a common laboratory setting.
