What is tension testing?
Tension testing, also called tensile testing, is a core mechanical test used to determine how a material behaves when subjected to a uniaxial tensile force. It measures properties such as strength, ductility and elasticity under controlled conditions.

Compression
Compression testing is a way of determining how something will react when a compressive force is applied to it. It typically involves measuring the relationship between the applied force and how much the object deforms.
It is performed to:
