Abstract
The stress variations in butt adhesive joints of dissimilar hollow cylinders under impact tensile loadings are analyzed in elastic and elasto-plastic deformation using a finite element method. The effect of Young's modulus of the adhesive and Young's modulus ratio between dissimilar adherends on the stress variations at the interfaces are examined. The characteristics of the stress variations in the joints under impact loadings are compared with those in the joints under the static loadings. As the results, it is found that the maximum value of the maximum principal stress occurs at the outside of the interface. The characteristics of the joints subjected to the impact loadings are found to be opposite to those subjected to the static loadings. In addition, the experiments were carried out to measure the strain response of the joints under impact tensile loads. Fairy good agreements are observed between the numerical and the measured results.
