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...
A Crack Phase-field Model to Analyze Aortic Dissections
Holzapfel, Gerhard A.; Gültekin, Osman; Hager, Sandra P.; Dal, Hüsnü (2019-09-05)
This study analyzes the lethal clinical condition of aortic dissections from a numerical point of view.On the basis of our previous contributions [1,2], we apply a holistic geometrical approach to fracture,namely the crack...
Phase-field approach to model fracture in human aorta
Gültekin, Osman; Holzapfel, Gerhard A.; Dal, Hüsnü (null; 2019-08-23)
Over the last decades the supra-physiological and pathological aspects of arterial tissues have become a prominent research topic in computational biomechanics in terms of constitutive modeling considering damage and fract...
A phase-field approach to viscoelastic fracture in rubbery polymers
Denli, Funda A.; Gültekin, Osman; Dal, Hüsnü (null; 2019-08-23)
Rubbery polymers are widely used in, e.g., the automotive, the aeronautical andspace industry. Rubbery polymers consist of network of long polymer chains responsible forthe elastic response and a secondary free chains supe...
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...
