Numerical investigations of the laminating effect in laminated beams

Serrano, Erik LU and Larsen, Hans Jörgen LU (1999) In Journal of Structural Engineering 125(7). p.740-745
Abstract
The paper presents numerical results concerning the so-called laminating effect of laminatedbeams. Using the finite-element method, it is shown that the assumption often made of a stress redistribution taking place around weak zones is not necessarily true. A fracture mechanics approach to a possible explanation for the laminating effect is also presented. Here a nonlinear fracture mechanics model is used to verify a hand-calculation formula based on linear elastic fracture mechanics. An important outcome is that, for an initially cracked laminated beam, the failure mode tends to be dominated by shear failure in the outermost lamination as the lamination thickness decreases.
