2 . a relevant formula of eight - node adhesive finite element is deduced in the paper , which is based on a separately interpolation scheme for reissner - mindlin plate element . a load capability analysis method for patched composite laminated structure is established by using tsai - hill failure criterion and thai ' s reduced stiffness scheme , and corresponding computer code is also developed 在任意四边形四节点复合材料层合板壳单元的基础上，推导了相应的八节点胶单元，并采用蔡-希尔强度理论以及蔡氏刚度退化准则，对复合材料层合板胶接补强结构进行刚度分析和极限承载能力分析，编制了相应的有限元分析程序。
