Abstract:

 

The aim of this study is to investigate failure strength and failure mode of  mechanically fastened carbon-epoxy composite plate which shape is trapezium. The failure load and mode are analyzed numerically. The numerical method includes two steps. First, the stress distribution in the plate is calculated by the use of a finite element method. Second, the failure load and the failure mode are predicted by means of Tsai-Hill and Tensilecompressive failure criterion. A computer code was developed which can be used to calculate the maximum failure load, the mode of failure and the propagation of failure. The edge, E/D, and side, W/D, distances of plate are changed from 1 to 4 and 2 to 4 respectively, while the orientation angle of plate is equal to 0°. It is found that full bearing strength is developed when the edge distance ratio is equal to 3 and side distance ratio is equal to 4.

 

Bu çalışmanın amacı, içinde pim bulunan yamuk şekilli, karbon-epoksi kompozitinin  yırtılma mukavemetini ve modunu araştırmaktır. Yırtılma yükü ve modu nümerik olarak analiz edildi. Nümerik metod iki adım içerir: ilk olarak plakadaki gerilme dağılımı sonlu elemanlar metodu kullanarak hesaplandı. İkinci olarak, yırtılma yükü ve modu Tsai-Hill ve Tensile-Compressive Failure kriterleri yardımıyla bulundu. Maksimum yırtılma yükü, Yırtılma modu ve Yırtılma ilerlemesini bulan bir bilgisayar programı geliştirildi. Fiber açısı  0° olmak üzere plakanın kenar oranı E/D ve genişlik oranı W/D sırayla 1 ile 4 ve 2 ile 4 oranında değiştirildi.
