| Abstract: | This paper presents a softening strip design of hybrid composite material. It is proved by means of theoretical analysis and experimental investigation that the softening strip can be used to prevent the crack propagation and to increase the residual strength of graphite/epoxy laminated composite plate. The influence of the crack size and the paramen-ters of the softening strips on the damage tolerance capability are also analysed. |
