New requirements in automotive industry demand lighter components with higher strength. In the last years, sheet metal forming processes at elevated temperatures have gained much importance due to the possibility of producing components with enhanced strength and geometrical accuracy and reduced mass. Finite element method is used in order to determine the formability of the component and perform the correct design of the tools before hot forming process. In this study, hot forming process and finite element analysis of hot forming simulations of high strength steels are reviewed with all steps from heating to cooling. Then, finite element model of a U channel profile with high strength steel material is performed and hot forming and cold forming processes are simulated and the results are compared. Thus, it is aimed that hot forming process has many advantages in order to produce structural components with high strength in automotive industry and usage of this process should be increased.

Otomotiv sanayindeki yeni gereksinimler, otomobillerin yüksek dayanımlı fakat daha hafif parçalar ile üretilmesini gerektirmektedir. Son zamanlarda yaygınlaşmaya başlayan ve yüksek mukavemetli çelikler kullanılan ve östenitleşme sıcaklığının üzerinde bir sıcaklıkta gerçekleştirilen sıcak şekillendirme işlemi, son derece dayanıklı, daha hafif ve doğru geometriye sahip parçaların üretilebilmesi sayesinde çok kullanışlı hale gelmiştir. Sıcak şekillendirme işlemi öncesi, parçanın şekillendirme analizinin yapılması, parçanın üretilebilirliğinin ve işlem sonuçlarının önceden görülebilmesi açısından sonlu elemanlar yöntemi kullanılmaktadır. Bu çalışmada, sıcak şekillendirme işlemindeki sac metalin ısıtılması işleminden metalin şekillendirilmesine, soğutulmasına ve sonraki işlemlere kadar tüm süreç açıklanmış ve sonlu elemanlar yöntemi ile yüksek mukavemetli çeliklerin sıcak şekillendirme süreci incelenmiştir. Ardından, yüksek mukavemetli çelik malzemeli U tünel profil parçanın sıcak ve soğuk şekillendirme simülasyonları gerçekleştirilerek sonuçlar incelenmiştir. Bu çalışma, sıcak şekillendirme işleminin otomotiv sektöründe yüksek dayanımlı yapısal parçaların üretimi için uygun olduğunun ve kullanımının yaygınlaştırılması gerektiğinin anlaşılmasını hedeflemektedir.
