Book Description
Test specimens are traditionally designed to produce a single stress state during the testing process resulting in limited data from individual tests. When material is not readily available, the use of a test specimen that generates a wide range of multiaxial stress states (and therefore more data per test) would be advantageous since this single specimen could replace a series of conventional specimens. Finite element (FE) techniques can be used to determine the stress states of interest in a component and then can be used to custom design a specimen to produce these stress states. The current work examines the use of FE techniques to custom design test specimens that would be more appropriate for typical pressure vessel geometries than traditional tensile test specimens. Stress states for thin and thick wall cylindrical sections are compared with those of standard (ASTM E8) and customized test specimens. An improved match between component and test specimen generated stress states is seen for the custom design specimen.
