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...
Two novel Kirchhoff plate finite elements for the modified strain gradient theory
Kandaz, Murat; Dal, Hüsnü (2019-11-18)
A Quasi-Incompressible and Quasi-Inextensible Finite Element Implementation of Fibrous Soft Biological Tissues
Gültekin, Osman; Rodoplu, Burak; Dal, Hüsnü (2019-09-11)
Fibrous soft biological tissues exhibit nearly incompressible exponentially stiffening mechanical response (J–like stress–strain curve), making the development of efficient and robust finite element formulations at the qu...
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...
