For 20 years ADMET's focus has been on producing leading edge mechanical testing systems that are reliable, exceed ASTM/ISO accuracy requirements, and are easy to learn and use. During this time we have remained steadfast to two founding principles; a willingness to tailor our systems to meet your needs; and to provide efficient and responsive customer service; thus giving you the confidence to test with certainty.

Typical points of interest when tensile testing a material include:
ultimate tensile strength or peak stress; modulus of elasticity, offset yield strength, which represents a point just beyond the onset of permanent deformation; and elongation at break.

The modulus of elasticity is calculated as the slope in the linear elastic region of the stress-strain curve.  The linear elastic region is prior to the proportional limit (see point A - Figure 1).  Beyond the proportional limit, the material undergoes permanent plastic deformation.
