Then compare the similar terms, we can obtain three new equations: (9) (10) (11) Solve the equation (9),(10) and (11),we can obtain , According to the equations (7) and ignore the high order of minuteness, we obtain the expression of the : And in the expression: The analysis of the example Use the usual membrane applied in the engineering as an example, calculate the large deflection and the small deflection of the center point of the membrane , and analyze the relationship of the two: so we have these figures, Figure2:The comparison of the large deflection and the small deflection under different pretension From the Figure2, we can find that: in the load region of -1.0 , the large deflection change along with the load is nonlinear; the deflection of the membrane become small while the pretension going up.
