Dynamic Mechanical Characterization of Granite under High Strain Rate
摘要
Abstract
In order to explore the variation law of the dynamic mechanical parameters of granite under impact load,the impact test of granite specimens was carried out by using the split Hopkinson pressure bar test(SHPB),and the test results showed that the peak stress of granite increased linearly with the increase of strain rate,showing an obvious strain rate effect.There is a positive correlation between the dynamic elastic modulus and the strain rate,the peak strain and the strain rate show an S-shaped function relationship,and the ultimate strain shows a linear increasing trend with the increase of the strain rate.关键词
