Why can’t I measure Young’s Modulus and Proof Stress in Metals using Crosshead Movement?

Young’s Modulus is the slope of the Stress v Strain curve measured from the origin of the curve. The initial strain in the test sample is very small so that any movement in the machine itself, in the load cell or any “take up” movement in the grips is large in comparison to the initial strain in the test sample.
The Dental School of Dublin requested some special attachments to be manufactured by Tinius Olsen. Tinius Olsen were supplied some examples of the test specimens, from which the special grips were designed and manufactured
Tinius Olsen can provide you with tensile test specimens that are suitable for use with split collet type tensile chucks. Specimens are supplied in lots of 50.
A variety of materials can be provided to enable the teaching and understanding of material science and strength characteristics.
We have now increased the range to include 0.4% and 1% Carbon steel to complement the existing O.15% Carbon Steel specimen.
There was a time when cans were all made from steel and used almost exclusively for preserve foods. Today they are made to a vast range of specifications for everything from drinks to deodorants. Assuring design performance and maintaining quality during manufacture is easily achieved with Tinius Olsen’s test machines and specially developed tooling.
Designers and marketing experts are demanding more than ever from the basic “tin can” in terms of materials used, loadings expected and performance features. Yet with these expectations comes the occasional failure – such as the “handy” ring pull that needs a large screw driver to prise it away from the can.
