Oluklu Çekirdekli Sandviç Panellerin Deformasyon Davranışı Üzerine Simulasyon Çalışması

Öz

Bu çalışmada, farklı oluklu çekirdek konfigürasyonlarına sahip sandviç panel yapılarının yarı statik eğilme yükü etkisi altındaki deformasyon davranışı sayısal olarak incelenmiştir. Oluklu çekirdek, dairesel, sinüzoidal, dikdörtgen, yamuk ve üçgen geometrilere sahip dökme poliamid (PA6) malzemeden oluşur. Sandviç panelde yüzey kabuğu olarak Alüminyum 6063-T5 plaka kullanılmıştır. Analiz sonuçlarına göre en yüksek deformasyon direncini 6363.6 N ile trapez çekirdekli sandviç panel sağlamıştır. Dairesel çekirdekli sandviç panel ise 4262.5 N ile en düşük deformasyon direncini göstermiştir. Özgül taşıma ve özgül enerji etme kapasitesi en yüksek olan sandviç panel trapez çekirdekli paneldir.

Simulation study on deformation behavior of sandwich panels with corrugated cores

Öz

In this study, the deformation behaviour of sandwich panels structures with different configurations of corrugated cores under the effect of quasi-static bending loading is investigated numerically. The corrugated core is consists of cast polyamide (PA6) material with circular, sinusoidal, rectangular, trapezoid, and triangular geometries. An Aluminum 6063-T5 plate is used as the skin of the sandwich panel. According to the analysis results, the sandwich panel with a trapezoidal core provided the highest deformation resistance with 6363.6 N. The circular core sandwich panel showed the lowest deformation resistance with 4262.5 N. The sandwich panel with the highest specific carrying and specific energy capacity is the trapezoidal core panel.
