| Abstract: | In this paper, a elastic-plastic dynamical constitutive model on jointed rock masses under blasting load is established with the help of the multiple rigid-body dynamics and contact-impact theory. On the basis of foe theory and foe structure of DYNA2D, and the abcve-mentioned model, numerical simulation is conducted and contours of stress in the different moments arc obtained in Jointed rock masses under blasting load. |
