Abstract

The small punch test method of characterizing material properties was introduced about thirty years ago. It has an advantage over conventional tensile test methods in that only a small sample of material is needed. A disadvantage of the method is that manufacture of the small hemispherical punch head is difficult and expensive due to the high dimensional accuracy requirements. Here an alternative design of punch is presented: a small punch beam test system consisting of a top die, a bottom die and a flat punch with semi-circular cross-section head. By coupling the numerical modelling and experimental results, a genetic algorithm has been used to characterize the material plastic properties.
