%X The dynamic constitutive relation of Bukit Timah granite under shock wave is obtained by the experiment using a light gas gun. For each experimental point, the process of stress-strain is monitored throughout the response with the respective preembedded pressure gauges. The sampled stress waves are then analyzed by Lagrange analysis method to arrive at quantitative constitutive relation. Under the state of one-dimensional strain, the stress of the granite depends on transient strain, strain rate and the strain rate history.Within the loading range, stress a can be represented by the polynomial of the strain and strain rate .
