    摘要:

    对含环向裂纹机身加筋壁板在轴向拉伸载荷作用下进行损伤容限试验,研究机身加筋壁板的裂纹扩展规律和剩余强度特性。借助ANSYS有限元软件对试验件进行应力强度因子分析,估算了裂纹扩展寿命;基于线弹性断裂力学准则和线弹性断裂力学加塑性修正准则,计算了剩余强度特征曲线,并进行了计算分析和试验结果的对比。研究结果表明:计算得到的裂纹扩展寿命与试验结果的相对误差为6.3%,满足工程要求。线弹性断裂力学加塑性修正准则估算的剩余强度更为合理,误差仅为2.6%。

    Abstract:

    Experimental study on a stiffened fuselage panel with circumferential crack subjected to axial tension load was presented. The performance of the crack growth and characteristic of the residual strength for fuselage panel were investigated by damage tolerance experiment. Stress intensity factors (SIF) of experimental structure were analyzed by using ANSYS software. The crack propagation life was evaluated. The residual strength curves were calculated based on the linear elastic fracture mechanics and linear elastic fracture criterion modified by yield correction, respectively. The research indicates analysis results agree well with the crack propagation test data. The relative error is 6.3%, and the calculation accuracy satisfies the requirement of engineering. The estimation results using linear elastic fracture criterion modified by yield correction is more reasonable than using linear elastic fracture mechanics. The relative error is 2.6%.
