| Abstract: | In this paper,the failure processes of composite laminates with multiple bolted joints under tension load were numerically simulated. The first crippling loads for several cases were obtained by two methods,a direct calculation method based on finite element models and an indirect method based on the load distribution.Compared with experiment results,the direct calculation method based on finite element models is effective and convenient,but the indirect method based on the load distribution is limited in scope.The conclusions are useful for the design of multiple-bolted composite joints in engineering programs. |
