Shear Strength Testing
National Technical Systems (NTS)
Many different loading schemes fall under the broad category of shear testing. Most often performed on small coupons of metals, composites and adhesives, these tests apply force or displacement until the specimen fractures. Single lap, double lap, short beam shear and torsion are typical configurations. All of these tests are designed to characterize materials under shear loading by determining shear-stress/shear-strain curves and material properties, including shear strengths and shear moduli.
