Turkey has made a significant progress in terms of aerospace and defense industries. The Atılım University Department of Aerospace Engineering opens to students in the Academic Year of 2020-2021, with the aim to train qualified engineers as required in the ever-developing aerospace industry. This department is a field of engineering that focuses on the R&D, design, manufacturing, testing and performance processes of aircraft such as planes, choppers, or rockets; as well as satellites, and other kinds of spacecraft. Located in Ankara where much of the work related to the aerospace studies takes place, our School is to offer common projects and long-term opportunities for internship studies with many companies in the industry. Our academic staff involves faculty members who are experienced in teaching aerospace engineering, as well as experts in the field after having worked in many projects in the defense industry, in addition to offering consulting. Backed with our state-of-the-art laboratories, our curriculum is to offer students a chance to acquire the skills and know-hows to advance Turkey in the sector. We aim to implement a hands-on approach in education by training our students with our aircraft in our hangar at Esenboğa Airport. We aim to provide them with a practical training, and a constant opportunity to touch, feel, and experience the aircraft, from the first year. Our focus is to have students experience the process of R&D, from the designing stage to prototype manufacturing. Our course content, devised to match the current needs of the sector, shall make it possible for our students to find employment in their fields of competence and interest.

Abstract

Functionally graded materials (FGMs) - categorized in advanced composite materials - are specially designed to reduce the stresses and failure due to material mismatches. Advances in manufacturing techniques have brought FGMs into use in a variety of applications. However, the numerical analysis is still challenging due to the difficulties in simulations of non-homogeneous material domains of complex parts. Presenting a numerical procedure that both facilitates the implementation of material non-homogeneity in geometrically complex mediums, and increases the accuracy of the calculations using a phase-field approach, this study investigates the usage of FGMs in dental prostheses. For this purpose, a porcelain fused to metal (PFM) mandibular first molar FGM crown is simulated and analyzed under the maximum masticatory bite force, and eventually the results are compared to a PFM crown prepared conventionally.
