Computational Modeling of Durability Phenomena in Concrete Ghasabeh, Mehran; Göktepe, Serdar (2018-10-10)
Computational modeling of self-assembly in deformable bodies Bilgin, Koçak; Göktepe, Serdar; Department of Civil Engineering (2021-9) Self-assembly is a process in which an irregular system transforms into a regular pattern or an organized structure through local interactions between the components of the material without any external influence. Therefore, self-assembly has great potential in the synthesis and manufacture of new materials. Although the main focus in the literature is mostly on self-assembly at the molecular level, there are many exciting applications of the self-assembling processes at larger scales. Space and time-varyin...
Computational Modeling of Shrinkage-Induced Cracking in Concrete Ghasabeh, Mehran; Göktepe, Serdar (null; 2019-09-09) 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 equat...
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 modelling of electro-active polymers Dal, Sinan Fırat; Göktepe, Serdar; Department of Civil Engineering (2019) This study is concerned with the stability of Electro-Active Polymers (EAPs) having geometries with periodic microstructures subjected to coupled electromechanical effects. For this purpose, coupled electromechanical equations, which are nonlinear, are discretized using the Finite Element Method (FEM) under the prescribed boundary conditions. EAPs are smart materials that may undergo large mechanical deformations when subjected to an electric field. Unlike many other materials that show permanent deformatio...
