Analytical and computational methods for a laterally graded surface loaded by a bonded piezoelectric thin film Dağ, Serkan; BALCİ, MEHMET NURULLAH (2025-01-01) Analytical and computational techniques are developed to carry out stress analyses for an advanced material system comprising a piezoelectric thin film bonded to a laterally graded half-plane. The piezoelectric thin film i...
Effects of translaminar edge crack and fiber angle on fracture toughness and crack propagation behaviors of laminated carbon fiber composites Asan, Ahmet Murat; Kaman, Mete Onur; Dağ, Serkan; Erdem, Serkan; Turan, Kadir (2024-06-01) In this study, the translaminar fracture toughness of carbon fiber laminated composites with different layer sequences was investigated experimentally and numerically for different crack directions. In the numerical study,...
Investigation of the translaminar fracture behavior of the fiber-reinforced composites stitched perpendicular to their plane Asan, Ahmet Murat; Kaman, Mete Onur; Dağ, Serkan; Erdem, Serkan; Turan, Kadir (2024-05-01) To increase the fracture toughness, the two-dimensional laminated textiles can be stitched with fibers throughout their thickness. But the stitch properties effect the mechanical behavior of the composite plates. Because o...
MAGNETOELECTROELASTIC RESPONSE OF FUNCTIONALLY GRADED MULTIFERROIC COATINGS UNDER MOVING HERTZIAN CONTACT Toktaş, Selim Ercihan; Dağ, Serkan (2024-01-01) A multilayer approach is developed to solve the moving Hertzian contact problem involving a circular punch and a functionally graded multiferroic coating. The mathematical model constructed consists of arbitrary numbers of...
Mechanics of moving contacts involving functionally graded multiferroics Toktaş, Selim Ercihan; Dağ, Serkan (2023-01-01) This article introduces solution procedures for moving contacts involving functionally graded multiferroic coatings. A moving rigid punch of a flat or a triangular profile is assumed to be in contact with a multi-layer med...
Cracking of a functionally graded coating due to sliding contact with heat generation Balcı, Mehmet Nurullah ; Dağ, Serkan; Yıldırım, Bora (2023-01-01) In this work, the thermal contact problem of a rigid flat punch sliding over functionally graded material (FGM) coating with a surface crack is investigated. The surface of a homogeneous isotropic substrate is ideally coat...
Computational elastodynamics of functionally graded thick-walled cylinders and annular coatings subjected to pressure shocks Abeidi, Abdelrahim; Dağ, Serkan (2022-12-01) A computational technique based on domain-boundary element method (D-BEM) is developed for elastodynamic analysis of functionally graded thick-walled cylinders and annular coatings subjected to pressure shock type of loadi...
Stresses in multi-layer coatings in Hertzian contact with a moving circular punch Toktaş, Selim Ercihan; Dağ, Serkan (2022-07-01) © 2022 Elsevier LtdThis article presents analytical solution procedures for moving Hertzian contact problems involving multi-layer and functionally graded coatings. A frictional circular punch is assumed to slide down the ...
Rastgele Derecelendirilmiş Kaplama ile Yarı-Dairesel Zımba Arasındaki Hareketli Temas Problemi Üzerine Toktaş, Selim Ercihan; Dağ, Serkan (2022-05-23)
Multi-layer model for moving contact problems of functionally graded coatings with general variations in physical properties Toktaş, Selim Ercihan; Dağ, Serkan (2022-04-01) This paper presents a multi-layer model for moving contact problems of functionally graded coatings whose physical properties have general spatial variations. The coating is assumed to be composed of an arbitrary number of...
