摘　　要：本文对在役压力容器表面凹坑的实验作了介绍,分析了凹坑处应力集中系数与凹坑几何参数之间的关系,给出了最大应力集中系数和应力分布的经验公式。This paper described the experiment of pits on surfaces of pressure vessels and investigated the relation between stress concetration coefficient and geometry shape of pits. The paper also gives the empirical formula of stress distribution and maximum coefficient of stress concentretion.
