Abstract
By assuming that triple point cracks are nucleated at zero time and grow only by grain boundary sliding, the time to fracture is estimated using two different fracture criteria. It is suggested that the method often used to calculate the effective surface energy of fracture may overestimate the true value by at least an order of magnitude.Keywords
