A series of quasi-static and dynamic compression tests were performed to obtain the stress-strain curves of phenolic resin within the strain-rate range of 10−4 ~ 103 s−1 firstly. In SHPB tests, smoothing technique was adopted to eliminate the high-frequency component by attaching a ‘tip’ material (shaper) in the form of a thin disc to the impact face of the loading bar, the ZWT nonlinear visco-elastic constitutive equation (10 parameters) was adopted to describe the mechanical characteristics of phenolic resin, and GAs was utilized to optimize the 10 parameters globally, the predicted results agree well with experimental results.
