An extended eight-chain model for hyperelastic and finite viscoelastic response of rubberlike materials: Theory, experiments and numerical aspects
Dal, Hüsnü; Gültekin, Osman; Açıkgöz, Kemal (Elsevier BV, 2020-12-01)
Rubberlike materials exhibit strong rate-dependent mechanical response which manifests itself in creep and relaxation tests as well as in the hysteresis curves under cyclic loading. Unlike linear viscoelasticity, creep and...
A quasi-incompressible and quasi-inextensible finite element analysis of fibrous soft biological tissues
Gultekin, Osman; Rodoplu, Burak; Dal, Hüsnü (Springer Science and Business Media LLC, 2020-06-01)
The contribution presents anextensionandapplicationof a recently proposed finite element formulation for quasi-inextensible and quasi-incompressible finite hyperelasticity to fibrous soft biological tissues and touches in ...
A phase-field model for fracture of unidirectional fiber-reinforced polymer matrix composites
Denli, Funda Aksu; Gultekin, Osman; Holzapfel, Gerhard A.; Dal, Hüsnü (Springer Science and Business Media LLC, 2020-04-01)
This study presents a crack phase-field approach for anisotropic continua to model, in particular, fracture of fiber-reinforced matrix composites. Starting with the variational formulation of the multi-field problem of fra...

Computational modeling of progressive damage and rupture in fibrous biological tissues: application to aortic dissection
Gültekin, Osman; Hager, Sandra Priska; Dal, Hüsnü; Holzapfel, Gerhard A. (Springer Science and Business Media LLC, 2019-5-15)
This study analyzes the lethal clinical condition of aortic dissections from a numerical point of view. On the basis of previous contributions by Gultekin et al. (Comput Methods Appl Mech Eng 312:542-566, 2016 and 331:23-5...
On the quasi-incompressible finite element analysis of anisotropic hyperelastic materials
Gueltekin, Osman; Dal, Hüsnü; Holzapfel, Gerhard A. (Springer Science and Business Media LLC, 2019-03-01)
Quasi-incompressible behavior is a desired feature in several constitutive models within the finite elasticity of solids, such as rubber-like materials and some fiber-reinforced soft biological tissues. The Q1P0 finite ele...
A quasi-incompressible and quasi-inextensible element formulation for transversely isotropic materials
Dal, Hüsnü (Wiley, 2019-01-06)
The contribution presents a new finite element formulation for quasi-inextensible and quasi-incompressible finite hyperelastic behavior of transeversely isotropic materials and addresses its computational aspects. The mate...
A comparative study on hyperelastic constitutive models on rubber: State of the art after 2006
Dal, Hüsnü; Badienia, Y.; Acikgoz, K.; Denli, F. A. (2019-01-01)
The micromechanically based network models are known to be superior over the purely phenomenological models in the analysis of unfilled rubber. However, various factors play a crucial role in the selection of the appropria...
Nonlinear compressible finite viscoleasticity of epoxy-based polymers
Dal, Hüsnü; Welschinger, F.; Gromala, P. J.; Han, B. (2019-01-01)
Epoxy-based polymers are widely used in the semiconductor industry as thermal and/or electrical interfaces and as encapsulating material. In the automotive industry, epoxy-based molding compounds (EMCs) are often used to p...
A three-scale compressible microsphere model for hyperelastic materials
Dal, Hüsnü; CANSIZ, Baris; MIEHE, Christian (Wiley, 2018-11-09)
This paper presents a seminumerical homogenization framework for porous hyperelastic materials that is open for any hyperelastic microresponse. The conventional analytical homogenization schemes do apply to a limited numbe...
