Opened in 2003 with the aim to graduate experts in the field of machine-production, our Department is among the firsts in our country to offer education in English. The Manufacturing Engineering program focuses on the manufacturing technologies that shape materials from raw materials to final products by means of analytical, experimental and numerical modeling methods. First Manufacturing Engineering Program to be engineered by Müdek, our department aims to graduate creative and innovative Manufacturing Engineers that are knowledgeable in the current technology, and are able to use production resources in an effective and sustainable way that never disregards environmental facts. As the first Department to implement the Cooperative Education Program at Atılım University in coordination with institutions from the industry, the Manufacturing Engineering offers a practice-oriented approach in education with its laboratory infrastructure and research opportunities. The curriculum at our department is supported by current engineering software, and catered to creating engineers equipped to meet the needs of the production industry.

Abstract

The aim of this study is to obtain higher plastic strains in the central gauge zone of the cruciform specimen under biaxial loading without compromising the simplicity of the specimen geometry and its manufacturing. The proposed novel geometry can be produced easily by a single machining operation performed on a cruciform geometry without requiring slits or any other operation on legs. Geometry of the specimen is determined through finite element analysis. It is observed that there are three characteristic regions with continuous transition in between, in the gauge of the specimen where material deforms under biaxial, plane-strain and uniaxial tensile conditions at the same time. Achieved biaxial strains are recorded to be as high as ever reported in the literature. Success of the geometry is demonstrated through experiments. (C) 2017 The Authors. Published by Elsevier Ltd.
