摘要
在 Hopkinson压杆上利用预留间隙法对花岗岩材料实施了高应变率动态实验 ,有效地避免加载波上升沿对这类脆性材料实验精度的影响 ,发现花岗岩材料有很明显的应变率硬化效应和损伤软化效应。
The high strain rate testing on granite is made on Hopkinson pressure bar with pre gapped method to avoid the influence of the loading wave rising edge on brittle materials. As a result, the granite material is of both strain rate hardening effect and damage softening effect apparently. The mechanics properties of granite under repetitive loading are also discussed.
