Tensile strength is defined as the stress at which a product, such as plastic strapping, steel strapping, rope, or wire, breaks or permanently disfigures.
There are three definitions of tensile strength:
- Yield Strength - The stress at which material strain changes from elastic deformation to plastic deformation, which means it is permanently deformed.
- Ultimate Strength - The maximum stress a material can withstand when subjected to tension, compression, or shearing. It is the maximum stress on the stress-strain curve.
- Breaking Strength- The stress coordinate on the stress-strain curve at the point of rupture.
In most poly strapping applications, the tensile strength is the average breaking strength.
