A finite element model based on the quasi-three dimensional displacement
field of Pipes and Pagano  with nonlinear strain-displacement relations is
developed to study the free edge problem of composite laminates. Numerical
results are presented to show the difference between the results of the nonlinear
and the linear analyses. It is observed that the stresses obtained in the nonlinear
analysis differ from the stresses obtained in the linear analysis by 10% in most
of the cases, and in some cases they differ as much as 40%.
