Free Edge Stress Fields in Composite Laminates

  • N. J. Pagano
Part of the Solid Mechanics and Its Applications book series (SMIA, volume 34)


A new theory to predict stress fields within composite laminates is employed to solve the free edge class of boundary value problems. In this theory, the stress field determination reduces to the solution of a one-dimensional problem. The solution involves consideration of 13N algebraic and ordinary differential equations. when N is the number of layers in the laminate. The general solution is valid for an arbitrary number of layers, however, numerical constraints limit the value of N which can be treated by the present approach.
