| 图17 厚壁圆柱动态破碎问题: 几何尺寸(左)和载荷时程(右). 圆柱内外半径分别为$r_\text{in}=80 \;\text{mm}$和$r_\text{out}=150 \;\text{mm}$, 平面外厚度为70 mm. 冲击载荷的幅值为$p_0=400\;\text{MPa}$, 参数$t_0=100$ $\mu$s |
| Fig.17 Fragmentation of a thick cylinder: Geometry (left) and the loading history (right). The innner and outer radii are $r_\text{in}=80 \;\text{mm}$ and $r_\text{out}=150 \;\text{mm}$, and the thickness is 70 mm. For the impact pressure, the amplitude is $p_0=400\;\text{MPa}$ and the parameter is $t_0=100$ $\mu$s |
