| 摘 要： | 本文从理论上分析了裂纹的扩展速度，并在此基础上对爆炸荷载作用下大理岩，水泥砂浆和有机玻璃中裂纹的扩展速度进行了实验测定和讨论分析，实测和分析结果表明，爆炸荷载作用下材料的裂纹扩展速度随时间的变化规律可以多项式曲线进行良好拟合。

| Abstract: | 0n the basis of theoretical analysis on crack spreading velocity in brittle materials,the experiments for measuring velocities of crack spreading in marble, cement mortarand organic gIass under exp1osion load are described in this paper. The results show thatthe relationship between velocity of crack spreading under explosi0n load and time canbe we1l fitted with polyn0mial curve. |
