In order to investigate the energy absorption properties of composite waved-beams,the dynamic impact tests of three types of composite waved-beam specimens which have the stacking sequences of[(±45)3/(0,90)/(±45)3],[(±45)8]and[(±45)7],were conducted to obtain the energy absorption load-displacement curves and the failure morphology was analyzed subsequently.Based on the continuum damage mechanics,a stiffness degraded model that involved extended Hashin failure criterion and damage evolution law was proposed...
