Abstract

Considering a steel type based on the behavior pattern of an alloy’s basic mechanical characteristics, a correlation has been found between the following: the characteristics of the ultimate fracture toughness of structural steels at the critical embrittlement onset temperature T_b in the compound stress state B_rNFb and B_rC0b and the fracture toughness in the uniaxial stress state B_rb through parameters that reflect the metal state in the loading elastic–plastic range. A method for the rational selection of structural steels for products that operate under the action of nonuniform force fields of different strengths has been developed.

应力集中下结构钢极限断裂韧性的估算

摘要

考虑到基于合金基本力学特性行为模式的钢种，发现以下各项之间的相关性：在复合应力状态B _rNFb下，在临界脆化起始温度T _b下结构钢的极限断裂韧性特性。和乙_{RC 0 b}，并在单轴应力状态下的断裂韧性乙_RB通过反映在装载弹塑性范围的金属状态的参数。已经开发了一种合理选择用于在不同强度的非均匀力场作用下工作的产品的结构钢的方法。
