Tensile Testing


Tensile testing is one of the most common ways of measuring material strength. It involves the linear stretching of a material until failure or some critical value is achieved. Tensile testing can be performed on most types of materials and gives information about yield strength, ultimate tensile strength, modulus of elasticity (stiffness), elongation, and other important properties.

Tensile testing is a reliable way to get data about how different processes may affect the performance of your final product – processes such as sterilization, extended aging periods, and exposure to various temperature and humidity conditions.

At DDL, our universal tester can not only perform tensile tests, but our large number of custom grips and fixtures allow us to perform many different types of procedures depending on your specific needs.
