摘要

为了研究不同表面裂纹参数对钢板断裂破坏的影响，采用有限元方法建立了钢板断裂破坏模型。结果表明:边缘表面裂纹对钢板断裂破坏的影响最大，对于非边缘表面裂纹，中心表面裂纹对钢板断裂破坏的影响最大。a/t越大，a/c越小，钢板越容易发生断裂破坏。a/c对K的变化规律和K最大值出现的位置有一定的影响。

Study on tensile fracture failure of a steel plate with a surface crack

In order to study the eﬀect of diﬀerent surface crack parameters on the fracture failure of steel plate, the model was established by FEM. The results showed that the edge surface crack has the greatest inﬂuence on the fracture failure of the steel plate, and for non-edge surface cracks, the central surface crack has the greatest inﬂuence on the fracture failure of the steel plate. The larger the a/t and the smaller the a/c , the easier the steel plate fracture failure occurs. The a/c has a certain inﬂuence on the variation law of K and the position where K max appears.
