摘要
本文对焊接接头在高速冲击加载条件下的冲击断裂韧性数据进行了分析研究,通过对试样冲击功、动态断裂韧性及其影响因素以及断口形貌进行分析,说明焊接接头在冲击载荷条件下的冲击断裂韧性受到焊接组配、焊接接头区域以及冲击速度的影响。在冲击载荷作用下,焊接接头的安全设计完全按传统的强度理论设计是不安全的,更应重视和优先考虑冲击断裂韧性的好坏。
The paper analyzes the dynamic fracturetoughness dates of welded joins with high impact loadingrate. Analysis of testing dates of impact work, dynamicfracture toughness and their effect factors showthat welded joints impact toughness and dynamicfracture toughness are affected by welded matching, zoneand loading rate. It is not safe that designing weldedjoins with impact loading under traditional intensitytheory. One should pay more attention to welded jointsimpact toughness and dynamic fracture toughness.
