摘要
本文采用霍普金森杆(S.H.P.B.)装置对三种磁铁矿和一种化岗岩在应变率为10~2～10·~3S^(-1)范围内的力学特性进行了研究。文中给出了矿岩在不同应变率下的动态破坏强度,动态弹性模量、动态应力-应变曲线和分析结论。
Split Hopkinson's Pressure Bar has been used to study the dynamic beva-vior of three kinds of magnetites and one granite at strain rates ranging from 300 to 1000s-1. Some results including the dynamic fracture strength, Young's modulus, stress-strain curve and constitutive equations of the rocks are given in this paper.
