Analytical and numerical analyses of transverse cracking in a cross-ply laminate — influence of the constraining effect

摘要: Abstract The restraint exerted by the two undamaged longitudinal layers of a cross-ply laminate on extension matrix cracks in central transverse layer is investigated from points view. First, relative contribution to whole strain energy release rate estimated through different already existing models. Then main features semi-analytical model recently proposed (with view deriving an approximate expression for stress field around front part-through-width crack) are described. related compared with that obtained five other
