爆炸作用下花岗岩动态本构关系试验研究

EXPERIMENTAL STUDY OF GRANITE'S CONSTITUTIVE RELATION UNDER BLASTING LOADING

建立了爆炸加载条件下岩石动态本构关系的实验和量测系统，通过研究认为平面波发生器是更适合于作为一般爆破实验室研究动态本构关系的手段。通过Ｌａｇｒａｎｇｅ分析方法对实测应变波形进行数值模拟，得到了试验范围内花岗岩的数值本构关系曲线和花岗岩的数值本构关系方程。

This paper establishes the experimental system of rock's constitutive relation under blasting loading and indicates that the planewave producer is a suitable method to study rock's constitutive relation in ordinary blasting laboratory.The numerical constitutive relation curves and equation of granite are obtained in experimental range,by numerical simulating of the measured strain waveforms with Lagrange analysis.
