摘　　要：采用条单元法分析了竖向裂缝对功能梯度板的热响应影响。功能梯度板的材料属性沿板厚方向连续线性变化,温度变化热源作用于带竖向裂缝的功能梯度板上。通过研究得出了裂缝距离热源不同位置、不同长度裂缝及不同频率温度变化热源等状态时,功能梯度板上表面的热响应情况。采用条单元法研究带竖向裂缝的功能梯度板的热响应问题,为带裂缝的功能梯度板的热研究提供了一定的指导。The thermal response of functionally graded material （FGM） plates with vertical cracks has been investigated based on the strip element method （SEM）. The material properties of the FGM plates vary continuously through the thickness. The thermal sources have been applied to the FGM plates with vertical cracks. The thermal responses are obtained by studying the different position of crack from heat source, different length cracks and different frequency of the FGM plates with vertical cracks using SEM provides heat source. The thermal response studying for some guidance for thermal problem.
