摘要

长期以来,焊接接头断裂一直是一个重要的研究和工业课题,焊接接头对保证焊接结构的安全运行和完整性起着关键作用。本文综述了微力学模型在焊接接头韧性断裂中的应用。与经典断裂力学方法相比,这些模型的主要优点是在预测损伤发展时考虑了局部量(应力和应变)。通过损伤参数的取值来量化损伤,损伤参数通常与金属材料韧性断裂的空洞形核、生长和聚并有关,即材料的描述可以与断裂过程中材料的实际行为联系起来。大多数介绍的研究,包括本文作者发表的研究,都是以钢为基材进行的,其余的研究涉及铝合金。

An overview of application of micromechanical models in ductile fracture analysis of welded joints
Fracture of welded joints has been an important research and industrial topic for a long time, having in mind the key role of welded joints in ensuring the safe operation and integrity of welded structures. This work contains an overview of application of micromechanical models to ductile fracture of welded joints. The main benefit of these models, in comparison with the classical fracture mechanics approach, is consideration of the local quantities (stress and strain) in prediction of damage development. The damage is quantified through the value of the damage parameter, which is typically related to the void nucleation, growth and coalescence for ductile fracture of metallic materials, i.e. the description of the material can be related to the actual material behaviour during fracture. Most of the presented studies, including those published by the present authors, are performed on steel as the base material, and the rest deal with aluminium alloys.
