Based on winkler assumption and mindlin ' s solution of displacement , elastic solutions for distributions of strain , axial force and bond stress are derived , and the influence of mechanical parameters to those are discussed . the elastic solutions are compared with results of testing , which indicate that the solution from winkler assumption can be well tallied with the test results 在一定的简化假设基础上,根据局部变形假定和mindlin位移解,分别推导出锚索注浆体内的粘结应力、轴力与应变分布公式,并将其与试验结果进行了对比分析,表明局部变形假定解与试验结果能够较好地吻合。
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。
