- Abstract
A Parametric design method for weak area structure of circle composite fragile cover was proposed by analysis of mechanical properties of circle composite fragile cover and weak area structure, which was confirmed by rush experiments. Firstly, boundary conditions of the weak area structure were determined by numerical simulation for circle composite fragile cover. Material parameters of weak area structure were simplified by classical lamination theory. Secondly, the strength of weak area structure was determined by numerical simulation under eleven different ratios of bending-stretching coupling load, and the strength envelopes were developed subsequently. Then the effect of thickness and length of lapped fiber layers on the strength of weak structure were discussed. According to maximum principle stress rule, the curves of strength and structure parameters versus different bending-stretching coupling load were presented and parametric design method of the weak structure was proposed. Lastly, two types of circle composite fragile cover was made for rush experiment. The results show: 1) Glue layer undertakes the tensile load, and loped glass cloth undertakes the sheer load. 2) The tensile strength is influenced by the thickness of lapped layers, while the shear strength is mainly affected by the length of glass cloth. 3) The theoretical results are in close agreement with the experimental data and the mean error is about 11%, which proves the feasibility of the proposed parametric design method
