Abstract

The magnetoelastic demagnetization of a number of steels in the delivery condition under longitudinal elastic tension, transverse compression, and impact has been investigated. The estimation of the magnetoelastic sensitivity of the studied steel grades in the linear approximation is given. The possibility of determining the tensile and compressive stress in the magnetoelastic memory mode with allowance for the magnetoelastic sensitivity of the selected section of steel is considered, and a method for its determination using dosed loading (impact or compression) is proposed. It is shown that the regression equation in the form of a polynomial is in satisfactory agreement with the experimental result.

测试钢中的单轴应力并考虑其磁弹性敏感性

摘要

已经研究了在纵向弹性拉伸、横向压缩和冲击下的交付条件下许多钢的磁弹性退磁。给出了线性近似中所研究钢种的磁致弹性灵敏度的估计。考虑了在磁弹性记忆模式下确定拉伸和压缩应力的可能性，同时考虑到所选钢的磁弹性敏感性，并提出了一种使用剂量加载（冲击或压缩）确定其的方法。结果表明，多项式形式的回归方程与实验结果吻合较好。
