For theories of partial differential equations about plates and shells, and mathematical theory on convergence and error estimates of the plate and shell elements, we refer to Bernadou (1993, 1996), Ciarlet (2000), and Chapelle and Bathe (2003).
In our discussion, we focus on the linear elements of Lagrangian family. For each node (N) of the mesh we define a base function N , such that N has value one at node N and zero at all other nodes. 4, we find that N has zero value at the boundary of the patch of these elements. This is why these base functions are named hat functions in some textbooks. 4 Shape function. 12) ≡ 1. In one of the neighboring elements of node N, for example, e , its Jth node nJ = N. The restriction of the base function N to e is called a shape function of element e , associated with node nJ , denoted by ϕ J .
This is commonly named as Reissner–Mindlin (R-M) theory. 3 are essentially applicable to R-M theory. We will investigate more in the following sections. 11) are in fact valid for general nonlinear applications. It is beneficial to explore the linear case at this point. Generally speaking, a robust theory or numerical algorithm for nonlinear analysis should perform well for the linear case as a reduced system. 3 is the system of governing equations for R-M plate theory.
