- Description
- Small Punch Static Testing is a testing methodology which has gained immense popularity in the power generation industry. With the drive to optimise material testing and use of expensive, lightweight materials in specialised engineering, Small Punch Static Testing has been standardised to determine standard mechanical properties of materials. Using the Small Punch Static Testing methodology as outlined in BS EN 10371, additively manufactured Ti-6Al-4V samples were tested in order to determine their theoretical ultimate tensile strength and yield strength and to determine whether there was a significant change in mechanical properties across the build height of an interrupted build direct energy deposition sample. While extremely material specific, this method has been proven to be feasible in determining mechanical properties in samples where material is scarce and no significant relationship between the sample extraction height and mechanical properties is noted.
