At. Yokobori, Difference in the creep and creep crack growth behaviour between creep ductile and brittle materials, ENG FRACT M, 62(1), 1999, pp. 61-78
By relating the creep crack growth versus time curve to the creep displacem
ent curve, different characteristics have been observed between creep-ducti
le and creep-brittle materials in a precracked or a notched specimen. In th
e present paper, an attempt has been made to further clarify these differen
ces by including the microstructural mechanism, the damage mechanics and co
ntinuum mechanical analysis. Based on the results, new ideas have been prop
osed for explaining the difference between the behaviour of creep-ductile a
nd creep-brittle materials in a precracked or a notched specimen. (C) 1998
