The brittle strength of orthotropic materials
網頁In rocks or rock-like materials, the constituents, e.g. quartz, calcite and biotite, as well as the microdefects have considerably different mechanical properties that make such materials heterogeneous at different degrees. The failure of materials subjected to external loads is a cracking process accompanied with stress redistribution due to material …網頁1975年4月1日 · A criterion of strength for transversely isotropic materials is obtained by direct application of the new results. For illustration, a quadratic strength function for …
