Abstract:

 In this study, T-shaped joints were designed from composites with different deltoid radius. For this purpose, carbon fiber woven fabrics were preferred as reinforcement elements. Then, tensile analyzes were performed on these composite T-joints. The effect of the deltoid radius on the maximum tensile load and damage behavior of the structure was examined. As a result of the analyses, fiber tensile-compression damage images occurring in the structure for each deltoid radius were obtained along with the load-displacement graph. The Hashin damage criterion was preferred for damage onset. Material Property Degradation MPDG method was used for damage progression in progressive damage analysis. By increasing the deltoid radius from 6 mm to 12 mm, the maximum contact load increased by approximately 10, and by increasing it to 18 mm, the maximum contact load increased by approximately 20.11. Fiber compression damage, spread over a wide area on the lower surface of the flange where it does not come into contact with the web, was determined to be the dominant damage type, and it was determined that this damage decreased with the increase of the deltoid radius. it was observed that as the deltoid radius increases, the T-jointed composite structure exhibits more rigid material behavior.

 Bu çalışmada farklı deltoit yarıçaplara sahip kompozitlerden T şeklinde birleşimler tasarlanmıştır. Bu amaçla takviye elemanı olarak karbon elyaf dokuma kumaşlar tercih edilmiştir. Daha sonra bu kompozit T-eklemleri üzerinde çekme analizleri yapılmıştır. Deltoit yarıçapının yapının maksimum çekme kuvvetine ve hasar davranışına etkisi incelenmiştir. Analizler sonucunda kuvvet-deplasman grafiği ile birlikte her deltoit yarıçap için yapıda meydana gelen fiber çekme-basma hasarı görüntüleri elde edilmiştir. Hasar başlangıcı için Hashin hasar kriteri tercih edilmiştir. Aşamalı hasar analizinde hasar ilerlemesi için Malzeme Özelliklerinin Bozulması MPDG yöntemi kullanılmıştır. Deltoit yarıçapının 6 mmden 12 mmye çıkarılmasıyla maksimum temas kuvveti yaklaşık 10 artmıştır. 18 mmye çıkarılmasıyla ise yaklaşık 20.11 yükseldiği belirlenmiştir. Flanşın ağ ile temas etmediği alt yüzeyinde geniş bir alana yayılan fiber basma hasarının baskın hasar tipi olduğu belirlenmiş ve deltoit yarıçapın artmasıyla bu hasarın azaldığı tespit edilmiştir. Deltoit yarıçapı arttıkça T bağlantılı kompozit yapının daha rijit malzeme davranışı sergilediği görülmüştür.
