提出了一种求解各向同性功能梯度材料二维瞬时导热问题的稳健非结构控制体积有限元方法。域中某一点的材料特性随空间坐标呈指数变化。空间离散采用三角网格，时间离散采用全隐式格式。研究了几个问题，并使用文献中提供的解析解和其他数值解成功地验证了结果。
A robust unstructured control-volume finite element method is presented for the solution of two-dimensional transient heat conduction in functionally graded materials (FGMs) with isotropic properties. The material properties at a point in the domain vary exponentially to spatial coordinates. A triangular mesh is chosen for spatial discretization and a fully implicit scheme is adapted for time discretization. Several problems are investigated and the results are successfully validated by using analytical and other numerical solutions available in the literature.
