AB  - Bu çalışmada, durgun çevre şartları altında hareketli ısı kaynağı ile bir yüzeyinden ısıtılan plakadaki sıcaklık ve termal gerilme dağılımlarının sayısal analizi yapılmaktadır. Hareketli ısı akısı profili olarak Gauss dağılımı seçilmiştir. Isı kaynağı z ekseni etrafında sabit açısal bir hızla (Ω) dönerken, plaka da eksenel yönde ilerleme hareketi yapmaktadır. Sayısal çözümler, çeliğin farklı ısı iletim katsayıları (λ = 10’dan 50 W/m-K’ne kadar) ve ısı kaynağının farklı Ω’ları (5 ve 10 rpm) için gerçekleştirilmektedir. Isı kaynağı, plakanın çok küçük bir bölgesine etki etmesinden dolayı uniform olmayan dik sıcaklık gradyantları oluşturmaktadır.
