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

This study focuses on the expansion of metallic micro rings under internal pressure using a grain level three dimensional finite element analysis in combination with a rate dependent crystal plasticity constitutive model. The size effect due to grain statistics such as grain orientations and number of grains through the thickness is investigated to a certain depth, in terms of final geometries and the scatter involved. The findings of the study could be used as the preliminary guidelines for suitable material selection in stretching dominated microforming operations. (C) 2014 Elsevier Ltd. All rights reserved.
