Abstract: Abstract In this study, the relaxation of free edge stresses in viscoelastic composite laminates is investigated by means of a stress function based viscoelastic model. A linear viscoelastic model using Prony series is adopted for… read more here.

Abstract: Abstract In composite laminates the layer-wise material mismatch induces highly localized stress concentrations at the free edges. This is referred to as free-edge effect. As a consequence interlaminar crack initiation may occur in addition to… read more here.

DOI: 10.1177/0021998318788915
Abstract: The effect of the free-edge on the interlaminar stresses that develop in a thin-ply [0°/90°]s laminated composite under uniaxial tension was explored using finite element models that directly modeled the random heterogeneous microstructure and a… read more here.
