The chevron V-notched bend bar specimen recently proposed as a practical approach to the fracture toughness testing of brittle materials has been further evaluated. The accuracy of the stress intensity expression has been improved through experimental analysis. The applicability of this specimen for

Stress intensity factor formulas and dimensionless compliance formula of chevron-notch three point bend specimen obtained by use of straight-through-crack assumption (STCA) and Bluhm's slice model have been presented. Two stress intensity factor coefficient formulas have been compared with the exper
The objective of the present study was to develop a reliable and statistically valid test to measure the fracture toughness of small specimens of bone, and by extension, prosthetic materials, using a compact sandwich specimen. Samples of bone were sandwiched between holders of a different material a
