Tensile Strength – Longitudinal

Longitudinal Tensile Strength – A sample of the prosthesis in its tubular form is placed with its ends in suitable jaws. It is then stretched at a uniform rate until the yield and/or break point is reached.

Equipment

A tensile strength machine, having a constant rate of traverse and suitable jaws is used to hold the sample prosthesis firmly without damaging its structure.
