This report summarises outcomes of a three year collaborative project on miniaturised testing between the Materials Centre at NPL and the IRC in Computer Aided Engineering at the University of Wales, Swansea. It also notes comments and remarks at an Interest Group meeting at NPL on 28 March 2007.
The collaborative project produced a numerical model of the small punch (SP) disc test and used this model to determine optimum testpiece and jig dimensions to maximise the sensitivity of the test. SP tests were conducted to validate the model. Uniaxial tests were undertaken in parallel with the SP tests, particularly on a thermally exposed ½Cr½Mo¼V steel, which demonstrated the ability of miniature testpieces to generate data that discriminated well between different material types. However, oxidation tests in the uniaxial test rig indicated that it would be sensible to conduct long term SP tests on Fe alloy samples in inert environments.
