CREEP OF ROCK BASED ON LONG-TERM EXPERIMENTS

Nabarro pointed out theoretically that any polycrystalline solid yields to an applied shear stress to change its shape due to self-diffusion within crystal grains. Since 1957 Kumagai and Ito have carried out the long-term creep experiment on granite beams. Their experimental results over 24 years show that granite flows viscously without a yield stress. It may be essential that a solid has no yield stress. Long-term creep experiments on rock are described, and the theory on creep by Nabarro and Herring is discussed. The number of the covering abstract of the congress is TRIS no. 385148. (TRRL)
