摘要
采用混合数值法分析了功能梯度材料板中瞬态热响应问题.功能梯度材料板的材料特性沿板厚方向连续变化,在梯度板中心作用温度变化的热源,此热源沿板厚方向连续分布.得出了温度变化对梯度板的影响,观测点处的位移响应与应力变化随时间分布的曲线以及瞬态的位移响应.研究表明,温度变化对板的作用效果与外载作用对板的作用效果是相当的.此研究是对混合数值法的在热领域应用的延伸与开拓,对热响应问题的研究具有一定的指导意义.
The transient thermal response of functionally graded material （FGM） plates has been investigated based on the hybrid numerical method （HNM）. The material properties of the FGM plates vary continuously through the thickness. The temperature is assumed to vary continuously through the thickness at the middle of the plate. The displacement response and stress are obtained for the FGM plates at the observation stations. It shows that the effect of the temperature to plate is equivalence with the effect of the force. This study is an extension for HNM and is of great significance in thermal domains.
