A comprehensive consideration of delamination location, delamination size and delamination quantity was focused to determine a quantitative evaluation of the influence of delamination on the tensile strength of T-stiffened panels under the out-of-plane tensile load. Moreover, the failure behavior of T-stiffened panels without delamination and those with delamination under tensile loading was also examined. A characteristic parameter about delamination in the stiffener/panel interface was proposed by means of the ratio (S_r) of the delamination size in the filler/panel interface to the filling area in the filler/panel interface. It is found that the delamination located closely to the stiffener/panel interface, especially closely to the filler/panel interface has the most significant influence on the tensile strength. Another interesting observation is that delamination in the stiffener/panel interface and the stiffener corner also changes the failure mode which cracks along the interior of panels near the adhesive layer.

综合考虑分层位置、分层大小和分层数量，定量评价分层对T型加筋板在面外拉伸载荷下拉伸强度的影响。此外，还检查了没有分层的 T 型加强板和在拉伸载荷下分层的 T 型加强板的破坏行为。通过比值（S _r) 填料/面板界面中的分层尺寸与填料/面板界面中的填充区域的关系。已经发现，紧贴加强板/面板界面的分层，特别是紧贴填充物/面板界面的分层，对拉伸强度的影响最大。另一个有趣的观察结果是，加强筋/面板界面和加强筋拐角处的分层也会改变失效模式，即沿着靠近粘合剂层的面板内部开裂。
