For any laminate which exists an obvious deviation between the estimation and experiment of static strength , maximum loads used in fatigue life predictions were obtained by multiplying the maximum loads used in tests with the ratios of analytical strength to test strength , so as to make the calculation feasible ( 3 )將iosipescu剪切強(qiáng)度試驗(yàn)方法推廣到剪切疲勞,對(duì)4準(zhǔn)各向同性層壓板試件進(jìn)行了剪切疲勞試驗(yàn)。用本文開(kāi)發(fā)的疲勞分析程序預(yù)測(cè)了被試多向?qū)訅喊宓募羟袕?qiáng)度和疲勞壽命,模擬了局部疲勞失效演變的過(guò)程。
