Abstract
A method is proposed for measuring the effective fracture surface energy (EFSE), and its variation with temperature, of materials which fail by wedge cracking. The results show reasonable agreement with EFSE values derived from creep data, and give temperature variations of the EFSE which are very similar to those obtained by other methods for other materials. The temperature variation of EFSE is further discussed in relation to the growth of cracks in high-temperature creep.Keywords
