根据力学性能和几何的对称性,本文对焊接接头非均匀体进行了分类。研究了更接近实际情况的力学性能非对称的焊接接头非均匀体的断裂特征参量,以及力学性能非对称性对裂纹开裂角的影响。
According to the mechanical properties and geometric symmetry, this paper classified the welded joint heterogeneous body. The fracture characteristic parameters of the non-uniform welded joint with mechanical properties that are closer to the actual conditions are studied, and the influence of the asymmetry of mechanical properties on the crack initiation angle is studied.
