概要

• 論文の詳細を見る

• Stresses in a slab with three orthotropic laminated layers are analyzed by the three-dimensional theory of transversely isotropic elasticity. The slab is subjected to transverse concentrated or distributed load at the center part on the top face. To obtain qualitative knowledge for delamination of carbon fiber reinforced plastic (CFRP) laminates, numerical results of interlaminar stresses are given for [0゜_n/90゜_n]_<sym> graphite/epoxy square laminates. It is shown that shear stresses on the upper interlaminar boundary are larger than those on the lower one. At each interlaminar boundary, shear stresses are maximal just below the concentrated load point or the edge of the distributed load area, although these stresses are zero at the center point.
