| 摘 要： | 传统的热应力分析是把热载荷当作静态或者准静态载荷来处理,在工程实际中如果温度的变化非常剧烈,则该方法不能满足需要,本文提出了一种结构在动态热载荷(包括热冲击)作用下响应的有限元求解方法,算例表明该方法是可行的、正确的.

| Abstract: | Traditional thermal stresses analyses consider thermal load as static load or quasi static load.When the temperature field of the structure varies drastically,these analyses can not satisfy the real need.A finite element method is presented for solving the response of structure under dynamic thermal load (including thermal impulse).A numerical example verifies the feasibility and validity of the presented method. |
