The Mathematical Models of Some Composite Elastic Structures and Their Finite Element Approximations
某些组合弹性结构的数学模型及其有限元逼近

In this paper, by means of the mathematical theory of composite elastic struc-tures and their finite element method, proposed by Feng Kang, mathematical modelsof some simple 3-dimensional and 2-dimensional elastic structures and their finiteelement approximations are investigated in detail.
