“…This procedure is based on many years of experience in the assessment of drawability evaluation methods and modeling of manufacturing processes [1][2][3][4][5]. The basis of numerical modelling are experience and good FEM simulation practice acoording to [15,16] and especially for Inconel superalloys [17][18][19][20][21].…”

The paper presents the study of drawability of thin sheet metals made of a nickel superalloy Inconel type. The manufacturing process of axisymmetric cup -cone and a closed section profile in the form of a circular tube were designed and analyzed. In both cases, working fluid-oil was used in place of the rigid tools. The process of forming liquid is currently the only alternative method for obtaining complex shapes, coatings, and especially if we do it with high-strength materials. In the case of nickel superalloys the search for efficient methods to manufacture of the shaped shell is one of the most considerable problems in aircraft industry [1][2][3][4][5]. However, the automotive industries have the same problem with so-called advanced high-strength steels (AHSS). Due to this, both industrial problems have been examined and the emphasis have been put on the process of liquid forming (hydroforming). The study includes physical tests and the corresponding numerical simulations performed, using the software Eta/Dynaform 5.9. Numerical analysis of the qualitative and quantitative forecasting enables the formability of materials with complex and unusual characteristics of the mechanical properties and forming technology. It has been found that only the computer aided design based on physical and numerical modeling, makes efficient plastic processing possible using a method of hydroforming. Drawability evaluation based on the determination of the mechanical properties of complex characteristics is an indispensable element of this design in the best practice of industrial manufacturing products made of thin sheet metals.

“…[1] Bu sistem ile proses adımları önemli ölçüde azaltılmış, çok parçalı sistemlerde ki parça sayısı da azaltılabilmiştir. Bu kapsamda otomotiv ve havacılık endüstrilerinde gerek boru şişirme gerekse de düzlemsel formdaki sac malzemelere hidrolik basınç uygulanması ile istenilen geometriler rahatlıkla elde edilebilmektedir.…”

ÖZYapılan bu çalışmada kesme operasyonunun özellikle son yıllarda birçok alanda yaygın olarak kullanılmaya başlanan hidro şekillendirme prosesine uyarlanabilirliğinin nümerik olarak değerlendirilmesi yapılmıştır. Nümerik çalışmalar kapsamında malzemenin kesilme yüzeyleri değerlendirilmiş ve çapak oluşum durumu zımbanın farklı hareketi için incelenmiştir. Modelleme çalışması kapsamında Johnson-Cook (J-C) pekleşme ve hasar modeli kullanılarak, hedeflenen proses parametrelerinde kesme durumunun gerçekleşip gerçekleşmediği belirlenmeye çalışılmıştır. Sonuç olarak hedef proses parametrelerinde 304 paslanmaz çeliğin bu proses ile kesilebilirliği gösterilmiştir.Anahtar Kelimeler: Hidro-kesme, Johnson-Cook hasar kriteri, 304 paslanmaz çeliği INVESTIGATION OF HYDRO-PIERCING METHOD FOR STAINLESS STEELS BY FINITE ELEMENT METHOD ABSTRACTIn this study, numerical evaluation of the adaptability of the cutting operation to the hydroforming process, which has been widely used in many areas especially in recent years, has been made. In the numerical studies, the cut surfaces of the material were evaluated and the burr formation state was investigated for the different movement of the punch. Within the scope of the modeling study, it was tried to determine whether the cutting condition in the target process parameters was realized by using the Johnson-Cook (J-C) hardening and damage model. As a result, 304 stainless steel can be cut by this process in target process parameters.
