用预埋于不同位置的压力探头，监测冲击产生的平面应为波在岩石试件中的应力历史波形。对应力波经过Lagrange分析得到BukitTimah花岗岩的动态本构关系。在一维应变状态下，BukitTimah花岗岩的应力依赖于瞬态应变和应变率，以及波动过程的应变率历史。
With pressure probes embedded in different locations, the plane where the impact is monitored should be the stress history waveform of the wave in the rock specimen. The dynamic constitutive relation of Bukit Timah granites was obtained by Lagrange analysis of stress waves. In one-dimensional strain states, the stress of Bukit Timah granite depends on the transient strain and strain rate, as well as the strain rate history of the fluctuating process.
