Lap Shear Testing

Lap shear testing is another type of test that can be considered a sub-category of adhesion testing. It is typically used to measure the strength of glues and adhesives and measures their strength when a load is applied. In a lap shear test two surfaces are bonded together and then pulled apart. Usually, the surface area where the adhesive is applied is specifically defined so that measurements such as PSI or Mpa can be calculated. Different types of lap shear testing can be performed, and careful consideration must be given to what a particular standard may require. Single lap shear, Single lap shear w/ a beveled sample, Double lap shear, and Double-butt lap shear are all various types of tests that fall within this category. United offers several types of grips and fixtures which will enable you to perform a variety of lap shear tests that are accurate and repeatable.
