| Abstract: | Fiber-reinforced composites have been widely used in aerospace and aircraft structures because of their excellent mechanical properties and light weight. Glass fiber reinforced epoxy composite(GFRC) truss with square cross section under three-point bending exhibits nonlinear behavior according to finite element analysis. On the Isight platform, a multi-parameter optimization method is conducted to obtain five key geometric parameters of the optimal composite truss which meets the demand of structural stiffness, load bearing and light weight. Finally, nonlinear structural responses of the optimal composite truss are obtained. |
