连续模型用于描述水平分层弹性系统的响应，该系统包含一个或多个增强片，这些增强片可能位于表面以下任何规定的深度。该分析基于线性弹性理论中众所周知的分层系统方程。基于与经典薄板理论中使用的分析类似的分析，通过指定层间边界条件来包含增强效应。给出了在具有不同弹性模量和增强刚度组合的两层系统表面施加轴对称载荷的情况下的数值结果。这些计算的结果代表了一个极限情况，当非线性和非弹性效应变小时，应该通过更通用的模型来接近该极限情况。此外，在许多预期正常工作负载的情况下，分析将为部件厚度和刚度的各种变化所产生的趋势提供良好的近似值。
A continuum model is used to describe the response of a horizontally layered elastic system containing one or more reinforcing sheets that may be located at any prescribed depth below the surface. The analysis is based on well-known equations for layered systems from the linear theory of elasticity. The effect of reinforcing is included by specifying the interlayer boundary conditions on the basis of an analysis that is similar to that used in the classical theory of thin plates. Numerical results are presented for the case of an axisymmetric load applied at the surface of a two-layered system with different combinations of elastic moduli and reinforcing stiffness. The results of these computations represent a limiting case that should be approached by more general models when nonlinear and inelastic effects are made small. Moreover, in many cases in which normal working loads are expected, the analysis will provide a good approximation for the trends that result from various changes in thickness and stiffness of the components.
