  “裂纹理论”译为未确定词的双语例句
     Under the complex loadings, the surface flaws of large complex structures and the original defects of materials would initiate the propagation of micro three-dimensional (3D) cracks, and result in catastrophic accidents. For the limitations of the traditional theories of two-dimensional cracks, the safety of actual structures containing 3D cracks cannot be guaranteed completely without the out-of-plane stress constraint.
