Sheet metal forming techniques are a major class of stamping and manufacturing processes of numerous parts such as doors, hoods, and fenders in the automotive and related supplier industries. Due to series of rolling processes employed in the sheet production phase, automotive sheet metals, typically, exhibit a significant variation in the mechanical properties especially in strength and an accurate description of their so-called plastic anisotropy and deformation behaviors are essential in the stamping process and methods engineering studies. One key gradient of any engineering plasticity modeling is to use an anisotropic yield criterion to be employed in an industrial content. In literature, several orthotropic yield functions have been proposed for these objectives and usually contain complex and nonlinear formulations leading to several difficulties in obtaining positive and convex functions. In recent years, homogenous polynomial type yield functions have taken a special attention due to their simple, flexible, and generalizable structure. Furthermore, the calculation of their first and second derivatives are quite straightforward, and this provides an important advantage in the implementation of these models into a finite element (FE) software. Therefore, this study focuses on the plasticity descriptions of homogeneous second, fourth and sixth order polynomials and the FE implementation of these yield functions. Finally, their performance in FE simulation of sheet metal cup drawing processes are presented in detail.

“…In addition, this test gives a preview of how sheet metal materials will behave during the press-forming process. Sheet materials are commonly converted into products by printing-forming methods (Karajibani et al 2017;Şener et al 2020;Vatansever & Esener 2019). It is thought that the experimental and numerical application of QS-PST to the material will be beneficial in overcoming the production problems encountered in this process.…”

In this study, Quasi-Static Punch Shear Test (QS-PST) for AISI-304 stainless steel sheet material with 0.5 mm thickness was performed experimentally and numerically, then the results were compared. QS-PST was designed non-standard according to the need and is especially used to determine the puncture resistance of composite plate materials against lowspeed loading. Since the results obtained from QS-PST are similar to those from ballistic tests, this has attracted the attention of researchers. The experimental study was carried out by integrating the die and punch which were specially produced for this test, into an electromechanical tensile-compression test device with a capacity of 100 kN. In order to define the material properties correctly in numerical analysis, the tensile tests of the relevant material were also carried out with the same device. Then, the CAD model of the experimental system was generated and Finite Element Analysis (FEA) was performed. In FEA, the mesh structure was determined as tetrahedral, since it gave closer results in such tests and the analyzes were performed by increasing the number of mesh from 16700 to 151800 elements. Finally, the experimentally and numerically obtained results were compared and it was observed that the result were very close depending on increasing the number of mesh.
