A topological approach to crack path detection and crack opening displacement calculation in phase-field models of fracture Babaoğlu, Muhittin; Kaynar, Ozan Özgür; Göktepe, Serdar (2026-08-15) As opposed to discrete approaches, the crack topology is approximated in a smeared manner in phase-field fracture models (PFMs) through a continuous order variable. Although this allows for avoiding the additional intricat...
Computational modeling of viscoelastic snap-through in mechanical metamaterials Dal, Sinan Fırat; Göktepe, Serdar (2026-07-01) Mechanical metamaterials are architected solids whose macroscopic response is governed primarily by geometry rather than composition. Instability-induced metamaterials form a crucial subclass within this group, harnessing ...
A non-iterative boundary element formulation for nonlinear viscoelasticity Akay, Ahmet Arda; Gürses, Ercan; Göktepe, Serdar (2024-06-01) In this study, we propose a non-iterative boundary element method (BEM) of highly nonlinear viscoelasticity in time domain. The computationally attractive iteration-free algorithmic structure is achieved by the linearizati...
Formulation of a Bilinear Traction-Separation Interface Law in Boundary Elements with Homogenization Akay, Ahmet Arda; Göktepe, Serdar; Gürses, Ercan (2024-01-01) Similar to most conventional composite materials, the interface is generally the weakest part of nanocomposites. For this reason, the behavior of the reinforcement-matrix interface is critical for determining the strength ...
Effects of the random walk and the maturation period in a diffusive predator–prey system with two discrete delays Bilazeroğlu, Şeyma; Göktepe, Serdar; Merdan, Hüseyin (2023-11-01)
Phase-field modeling of thermal cracking in hardening mass concrete Ghasabeh, Mehran; Göktepe, Serdar (2023-09-01) The manuscript is concerned with the phase-field modeling of thermal cracking in massive hardening concrete structures. Owing to the exothermic reactions, known as hydration, a considerable amount of heat is generated duri...
A new time-domain boundary element formulation for generalized models of viscoelasticity Akay, Ahmet Arda; Gürses, Ercan; Göktepe, Serdar (2023-05-01) The contribution is concerned with the novel algorithmic formulation for generalized models of viscoelasticity under quasi-static conditions within the framework of the boundary element method (BEM). The proposed update al...
Modeling permanent deformation during low-cycle fatigue: Application to the pelvic floor muscles during labor Vila Pouca, M.C.P.; Areias, P.; Göktepe, Serdar; Ashton-Miller, J.A.; Natal Jorge, R.M.; Parente, M.P.L. (2022-07-01) © 2022Low cycle fatigue (between two to hundreds of cycles) is associated with large permanent strains and the development of microdamage that can start as soon as the first cycle. It has been identified as a possible dama...
