| 摘 要： | 用有限元方法数值模拟了脉冲激光作用于铝管时所产生的温升情况。比较了物理参数随温度变化和不随温度变化两种情况下的温度场的区别,分别给出了两种情况下的温度随角向的分布曲线。结果表明:物理参数随温度的变化对整个瞬态温度场的影响很大,为在热弹条件下在激光激发管状材料时的超声导波的研究提供了定量的基础。 |

| Abstract: | The transient temperature fields generated by a pulsed laser in aluminum pipe are obtained by using the finite element method. The difference of temperature fields between considering and neglecting temperature-dependence of material parameters is compared, and the temperature distributions of aluminum pipe are obtained in angular orientation at various time. The temperature-dependence of material properties has a great influence on the temperature fields indicated by the numerical results. |
| Keywords: | pulsed laser ultrasound transient temperature field finite element method |
