Abstract
The dynamic strength of an adhesively bonded single lap joint was investigated analytically and experimentally. Stress distributions and the variation of stress with time in the joint were analyzed by FEM. The dynamic strength of the joint under impact loading was calculated by applying failure criteria to the stress distribution. The strength of the joint was measured experimentally using a drop-weight testing machine. The analytical prediction of the strength agreed to the experimental result. The dynamic strength of the joints increases with increasing lap length. The effects of increasing lap length on strength decrease when the lap length is large.
