This contribution is concerned with the computational modeling of durability problems related to drying shrinkage. The associated formulations are conducted by developing a coupled constitutive modeling approach, which is furnished by the robust computational tools within the framework of poroviscoelasticity. In contrast to the existing studies, we employ a physically motivated technique where the pore pressure is obtained as a function of the water content that is determined using sorption‐desorption equations for a given value of the local relative humidity. Therefore, the proposed model accounts for the hygro‐chemo‐mechanical cross coupling effects between the shrinkage‐induced strain development due to the pressure evolution through humidity variations and the stress concentrations in hardening and hardened viscoelastic concrete. The comparison of the numerical examples with experiments …

Computational Modeling of Drying Shrinkage in Early-Age Concrete Ghasabeh, Mehran; Göktepe, Serdar (2019-10-10) This contribution is concerned with the computational modeling of durability problems related to drying shrinkage. The associated formulations are conducted by developing a coupled constitutive modeling approach, which is furnished by the robust computational tools within the framework of poroviscoelasticity.

Computational modeling of thermal and shrinkage-induced cracking in concrete Ghasabeh, Mehran; Göktepe, Serdar; Yaman, İsmail Özgür; Department of Civil Engineering (2021-3-3) This work is concerned with the computational modeling of thermal and shrinkage-induced cracking in concrete. Thermal and hygral gradients develop within concrete structures of varying sizes and aspect ratios due to the intrinsic physicochemical phenomena accompanied by adverse environmental effects. These spatio-temporal gradients invariably result in uneven volumetric deformations that can cause stress concentrations when the concrete is sufficiently rigid. Then, when the gained tensile strength is lower ...
Computational Methods for Inclined Cracks in Orthotropic Functionally Graded Materials Under Thermal Stresses Dağ, Serkan; TOPAL, SERRA (2013-10-03) This article sets forth two different computational methods developed to evaluate fracture parameters for inclined cracks lying in orthotropic functionally graded materials, that are under the effect of thermal stresses. The first method is based on the J(k)-integral, whereas the second entails the use of the J(1)-integral and the asymptotic displacement fields. The procedures introduced are implemented by means of the finite element method and integrated into a general purpose finite element analysis softw...
Numerical simulation and analytical optimization of microchannel heat sinks Türkakar, Göker; Okutucu Özyurt, Hanife Tuba; Department of Mechanical Engineering (2010) This study has two main objectives: The performance evaluation of existing microchannel heat sinks using a CFD model, and the dimensional optimization of various heat sinks by minimizing the total thermal resistance. For the analyses, the geometric modeling is performed using the software GAMBIT while the thermal analysis is performed with FLUENT. The developed model compares very well with those available in the literature. Eight different metal-polymer microchannel heat sinks are analyzed using the model ...
Analytical modeling of fiber reinforced composite deep beams Yağmur, Eren; Burak Bakır, Burcu; Department of Civil Engineering (2018) Discrete fibers are often used as reinforcement to increase the tensile and shear strengths of concrete. For many years, the behavior of fiber reinforced composite members has been investigated both experimentally and analytically. The influence of fibers on the behavior of shear critical members is quite significant, therefore, it is inevitable to develop a method, which estimates the shear strength of fiber reinforced composite deep beams realistically. This is why one of the main objectives of this study...
