中文摘要 | 本文目的在建立多層膠合複合層板有限元素法模式,以分析利用單邊補片及雙邊 補片膠合補強已脫層之複材層疊板,有限元素模式以Mindlin-Reissner板理論加入平面影 響,並考慮膠層橫向剪應力及橫向正應力在各層板厚度分佈,利用變分原理推導膠層與各 層板之廣義應力應變關係修正式,再以所建立公式推導多層膠合複材層板分析之有限元素 法。在本文中並分析以單邊補片及雙邊補片膠合補強脫層複材層疊板挫屈載重及挫屈型 態,並探討補片厚度對脫層複材板補強效果的影響。 |
英文摘要 | Finite element models for multilayered adhesive-bonded composite laminated plates are established for analyzing single-sided and double-sided repair composite laminated plates with delamination. The model is based on the Reissner-Mindlin plate theory with an assumed variation of the transverse shear and normal stresses through the thickness of layer. The generalized stress strain relations of multilayered adhesive-bonded composite laminated plates are established by using a variational principle. According to this formulation, finite element models for multilayered adhesive-bonded composite laminated plates are developed. The buckling load and mode shape of single-sided and double-sided repair composite laminated plates with delamination can be obtained by the present method. The study also explores the influences of patch thickness on buckling load and mode shape in repair composite laminated plates with delamination. |
