Bu çalışmada, literatürde “Vibratory Stress Relief” adıyla bilinen “Titreşimli Gerilim Giderme” yöntemi, ANSYS programı aracılığıyla sonlu elemanlar yöntemi kullanılarak simüle edilmiştir. Paslanmaz çelik ve alüminyum malzeme kullanılarak modellenen üç farklı geometrideki öngerilmeli plakalar, üçer farklı öngerilme durumu için incelenmiştir. Öngerilmeli plaka oluşturabilmek için öncelikle plakaya yer değiştirme uygulanmış ve sonrasında serbest bırakılmıştır. Uygulanan yer değiştirme miktarı ile farklı değerlerde üçer öngerilme durumu yaratılmıştır. Öngerilmeli plakanın birinci rezonans frekansı tespit edilmiş ve devamında farklı genlik miktarlarında gerilim giderme işlemi gerçekleştirilmiştir. Kare ve iki farklı dikdörtgen geometriye sahip plakalarda gerçekleştirilen ANSYS simulasyonlarına göre, paslanmaz çelik için %80 ile %95 arasında artık gerilme değerlerinin azaldığı görülürken alüminyum için ise bu aralığın %71 ile %91 bandında olduğu görülmüştür. Ayrıca her bir plaka için oluşturulan gerinim-gerilme grafiklerine göre, yapı içerisindeki öngerilme miktarının, farklı genlik değerlerindeki titreşimler ile farklı oranlarda azaldığı tespit edilmiştir. Öngerilme miktarının artmasıyla plakalara uygulanabilecek titreşimli gerilim giderme genliği aralığının da arttığı görülmektedir.

In this study, the “Vibratory Stress Relief” method, known as “Titreşimli Gerilim Giderme” in the Turkish literature, is simulated using the finite element method through the ANSYS. Prestressed plates in three different geometries, which are modeled using stainless steel and aluminum materials that are not suitable for conventional heat treatment, are examined for three different prestressed conditions. In order to model a prestressed plate, the plate is first displaced and then released. Three prestressed conditions at different values are modelled. The first resonance frequency of the prestressed plate is determined and
then stress relief is performed at different amplitudes. According to ANSYS simulations, it is observed that the residual stress values decreased between 80% and 95% for stainless steel in different situations, while this range is between 71% and 91% for aluminum. According to strain-stress graphs, it is observed that the prestress value in the structure decreases at different rates with vibrations at different amplitudes, while the range of vibration stress relief amplitude that can be applied to the plates expands with the increasing the amount of prestress.
