摘要为了研究长径比和应变率对海泡石的破碎能耗影响,采用分离式霍普金森压杆(SHPB)对三组不同长径比的海泡石试样在不同应变率下进行动态压缩试验。结果表明:在同种长径比试样中,随着应变率的增加,海泡石试样的应力-应变曲线表现出不同的变化规律。当长径比相同时,应变率越高,海泡石试样的吸收能越大,使得压碎后的碎块尺寸更小且粉末增多。同等水平应变率下,随着长径比增加,海泡石试样的峰值应力不断减小且吸收能不断增大,破碎形态由劈裂变为压碎。当长径比越大且应变率越高时,海泡石试样的破碎程度越大且破碎效果越好。

Abstract: In order to study the influence of aspect ratio and strain rate on the energy dissipation of sepiolite crushing, the split Hopkinson pressure bar (SHPB) was used to perform the dynamic compression tests on three sepiolite specimens with different aspect ratios under different strain rates. The results show that with the increase of the aspect ratio, the stress-strain curves of the sepiolite with the same aspect ratio have shown different changing laws. Under the same aspect ratio, the higher the strain rate is, the greater the absorption energy of the sepiolite sample will be, which will make the size of the broken pieces smaller and the number of powder increases. At the same level of strain rate, with the increase of the aspect ratio, the peak stress of the sepiolite sample keeps decreasing but the absorption energy increasing, and the broken form of the sepiolite sample changes from splitting to crushing. When the aspect ratio is larger and the strain rate is higher, the breaking degree of the sepiolite sample is greater and the breaking effect is better.

Key words: epiolite aspect ratio strain rate crushing energy dissipation
