An efficient method for solving fractional integral and differential equations of Bratu type
Aydınlık, Soner; Kırış, Ahmet (Işık University Press, 2024-01)In this paper, the fractional integral and differential equations of Bratu type, which arise in many important physical phenomena, are investigated by an effective technique, Chebyshev Finite Difference Method with the ... -
Eshelby tensors for a spherical inclusion in microelongated elastic fields
Kırış, Ahmet; İnan, Esin (Pergamon-Elsevier Science ltd, 2005-01)Eshelby tensors are found for a spherical inclusion in a microelongated elastic field. Here. a special micromorphic model is introduced to describe the damaged material which defines the damage as the formation and the ... -
Eshelby tensors for a spherical inclusion in microstretch elastic fields
Kırış, Ahmet; İnan, Esin (Elsevier Ltd, 2006-08)In the present work, microelastic and macroelastic fields are presented for the case of spherical inclusions embedded in an infinite microstretch material using the concept of Green's functions. The Eshelby tensors are ... -
Estimation of microstretch elastic moduli by the use of vibrational data
Kırış, Ahmet; İnan, Esin (Springer, 2007)In the present work, a nonlinear wave theory is used for the estimation of the material properties of a "microstretch" medium. For this purpose a thin plate is considered and triplicate Chebyshev polynomial series are used ... -
Free vibration of composite sandwich beams with microstretch viscoelastic core
Aydınlık, Soner; Kırış, Ahmet; İnan, Esin (Springer Science and Business Media Deutschland GmbH, 2021)In the present work, we studied a sandwich beam which is made of two thin stiff layers on top and bottom and a microstretch viscoelastic core in the middle. Here, the top and the bottom stiff layers are considered as ... -
A hollow cylinder problem in microstretch theory
İnan, Esin; Kırış, Ahmet (Springer-Verlag, 2011)A hollow cylinder micro-damaged tube under pressure problem is discussed. Micro damage is modeled with Eringen's microstretch theory and the displacement and its comparison with classical result are given. -
On the identification of microstretch elastic moduli of materials by using vibration data of plates
Kırış, Ahmet; İnan, Esin (Pergamon-Elsevier Science LTD, 2008-06)In the present work, the vibration problems of rectangular plates modeled by Eringen's microstretch theory are investigated for the identification of the upper bounds of the microstretch moduli of the plate material. The ... -
Thermo-microstretch elastic bodies and plane waves
İnan, Esin; Kırış, Ahmet (IOP PUBLISHING LTD, 2011)In the present work, vibration problems of rectangular plates are considered for the determination of upper bounds to the unknown microstretch material properties. The frequencies are obtained by extending the Ritz method ...
