Design
of mechanical components against fatigue is vitally important to prevent sudden
and unexpected fatigue damage. Due to the complex nature of welded joints
because of the changes in material properties due to heat and the geometry of weld
beads, designing against fatigue becomes an even more challenging task. Over
the years, several methods that can accurately and effectively determine
fatigue related parameters were developed. In this paper, a state of the art
literature review of studies based on strain energy density (SED) approaches
and their use in fatigue evaluations are presented. While a theoretical
background is provided, the main focus of the paper is to highlight
applications of SED approaches. In order to achieve this objective, papers with
varied topics that related to SED are evaluated.

Mekanik bileşenlerin
yorulmaya karşı tasarımları ani ve beklenmedik yorulma hasarlarını önlemek için
hayati önem taşır. Kaynaklı bağlantıların ısı sebebiyle değişen malzeme
özellikleri ve kaynak dikişlerinin geometrisinden kaynaklanan karmaşık doğası
sebebiyle, yorulmaya karşı tasarlanmaları çok daha zorlu bir görev haline
gelmiştir. Yıllar içinde yorulma ile ilgili parametreleri hassas ve efektif
şekilde belirleyebilecek yöntemler geliştirilmiştir. Bu makalede, birim şekil
değiştirme enerji yoğunluğu yaklaşımlarına ve onların yorulma incelemelerinde
kullanımlarına dayanan çalışmaların güncel bir literatür incelemesi
sunulmuştur. Teorik bir temelin verilmesi ile birlikte, bu makalenin ana odağı
birim şekil değiştirme enerji yoğunluğu yaklaşımlarının uygulamalarını
vurgulamaktır. Bu amacı yerine getirmek için, birim şekil değiştirme enerji
yoğunluğu ile ilgili çeşitli konulara sahip makaleler incelenmiştir.
