Assessment of Brittle Fracture Properties by Small Punch Test
Original language description
Small punch test is an advantageous method for evaluation of mechanical properties of components because much less material is required for sampling and subsequent material testing. This is especially valuable in cases where not enough bulk material is available, and the repair of sampled place is complicated e.g. power industry. The testing material is sampled by a special sampling device that ensures no component damage and the sampled volume is so small that no component repair is necessary after sampling. Small punch testing is viable not only for evaluation of mechanical properties but can also be used for evaluation of brittle fracture properties (transition temperature, fracture toughness), which play integral part in lifetime of some power components and structures. This paper introduces and compares two different approaches to the evaluation of the transition temperature. Also, a way to evaluate J-integral value using small disc specimen with side notch which is suggested by EN 10 371 standard is introduced and compared to J-integral evaluation via standard fracture mechanics approach using multiple CT specimens and plotting crack growth resistance curve.
