Özet
Bu çalışmada; alüminyum alaşımıAA6063’ den yapılmış farklı koniklik açısı (0°, 5° ve 10°) ve eksenel doğrultuda farklı kalınlığa (0,5 mm - 4 mm) sahip bölgelerden oluşmuş fonksiyonel derecelendirilmiş tüplerin (FDT) enerji sönümleme davranışları sayısal olarak incelenmiştir. Analizler sonucunda tüplerin deformasyon şekilleri, kuvvet-yer değiştirme ve enerji-zaman grafikleri elde edilmiştir. Farklı koniklik açıları için en düşük pik kuvvet ve en yüksek özgül enerji sönümleme (ÖES) değerlerini sağlayan optimum bölge kalınlıkları, İleri Beslemeli Yapay Sinir Ağları (İBYSA) tekniğini içeren optimizasyon yöntemi ile belirlenmiştir. Optimizasyon sonucunda elde edilen katman kalınlıkları fonksiyonel derecelendirilmiş tüpün enerji sönümleme davranışını iyileştirdiği görülmüştür.
