Abstract

In this study, sixteen models are designed with reentrant honeycomb geometry with different angles. Using the finite element method (FEM), a displacement on the horizontal axis is applied to the designed models and the vertical displacement values resulting from the applied horizontal displacement are determined and compared. Accordingly, with a horizontal displacement of 2 mm, the ratio of vertical strain to horizontal strain is found to be 2.51%, which is the highest, and 2.01%, which is the lowest. It is observed that the equivalent stresses increase with increasing angles in the design.

Özet

Bu çalışmada, farklı açılara sahip girintili ökzetik geometrisine sahip on altı model tasarlanmıştır. Sonlu elemanlar yöntemi kullanılarak, tasarlanan modellere yatay eksende 2 mm yer değiştirme uygulanmış ve uygulanan yatay yer değiştirmeden kaynaklanan düşey yer değiştirme değerleri belirlenerek karşılaştırılmıştır. Buna göre, 2 mm yatay yer değiştirmede, düşey gerinim/yatay gerinim oranı en yüksek %2.51, en düşük %2.01 olarak bulunmuştur. Ayrıca, modelde oluşan karşılaştırmalı gerilmelerin, tasarımdaki artan açılarla birlikte arttığı da gözlemlenmiştir.
