Mixed Boundary Value 2-D Elasticity Problems of Structural Elements of Composite Materials

摘要

Now-a-days, almost all the engineering structural elements, such as plates, shells, beams, etc., are made of composite materials because of their superior mechanical and physical properties, namely, high specific strength, stiffness, and density. The boundaries of these structural elements are always subjected to constraints or loadings applied by the adjacent elements or other supports. Very often, the boundary conditions are of mixed type. Therefore, it is imperative to analyze these elements under actual boundary conditions to understand, quantify, and improve their elastic characteristics. Numerical techniques, e.g., finite difference and finite element methods, can be employed for the analysis of these elements. However, the accuracy of the results,
