举一反三
- When the soil reaches the limit equilibrium state, the location of shear failure surface must be on the maximum shear stress surface（ ） A: 正确 B: 错误
- In Mohr-Coulomb failure criterion, failure occurs when the ______ is achieved and not when the maximum shear stress is achieved.
- 中国大学MOOC: For a bar under axial tension, the sections with the maximum normal stress and maximum shear stress are
- The failure modes of foundation include general shear failure, local shear failure and punching shear failure（ ）
- Which of the following statements is correct ? (1) There are two types of stress, normal stress(σ) and shear stress(τ). (2) On one section, the normal stress(σ) and the shear stress(τ) must be perpendicular to each other. (3) On one section, all the normal stress(σ) must be equal in size and same in the direction. (4) On one section, all the shear stress(τ) must be parallel.
