... such as stress and stiffness can be determined by solving the associated initial-boundary value problem. Data on indentation force ( f ) and depth ( δ ) are often interpreted using a classical 19th century solution by Hertz for the localized indentation of a semi-infinite half-space that exhibits...

... carotid biaxial stiffness stress energy dissipation regional variations The elastin-associated glycoprotein fibulin-5 is essential for effective elastogenesis, particularly via the cross-linking of tropoelastin [ 1 ]. Whereas deficiencies in the elastin-associated glycoproteins fibrillin-1...

... be addressed in future studies. Finally, the initial state of stress of the non-pressurized samples of isolated liver parenchyma tested in the current study is likely different from the initial state of stress of the liver in vivo due to blood pressure and contact with surrounding tissues. However...

...Habiba Bougherara; Ehsan Rahim; Suraj Shah; Anton Dubov; Emil H. Schemitsch; Rad Zdero With the resurgence of composite materials in orthopaedic applications, a rigorous assessment of stress is needed to predict any failure of bone-implant systems. For current biomechanics research, strain gage...

... artery was tested after storage for 1–28 days in physiologic saline at 4°C. There were no significant effects of storage time on the arterial diameter or force at each pressure, but there were significant effects on the stretch ratio and stress at each pressure. The significant effects on the stretch...

...Zhongzhao Teng; Umar Sadat; Guangyu Ji; Chengcheng Zhu; Victoria E. Young; Martin J. Graves; Jonathan H. Gillard High mechanical stress condition over the fibrous cap (FC) has been widely accepted as a contributor to plaque rupture. The relationships between the stress, lumen curvature, and FC...

... not be adequate as the geometry of the cerebral ventricles is unique. In this study, a three-dimensional (3D) finite element model of the cerebral ventricles during hydrocephalus is presented. Results from this model show that during hydrocephalus, the periventricular regions experience the highest stress...

...Laura Hansen; William Wan; Rudolph L. Gleason Good predictions of the local mechanical environment of the tissue with known geometry and applied loads are fundamental to quantifying the biological response of tissues to mechanical stimuli. Whereas mean stresses in cylindrical sections of blood...

... in caliber that is needed to maintain wall shear stress near its homeostatic level and the longer term changes in wall thickness that are needed to maintain circumferential wall stress near its homeostatic target. Moreover, it is shown that competing effects of intramural and wall shear stress-regulated...

...Baoshun Ma; Jia Lu; Robert E Harbaugh; Madhavan L. Raghavan Background. Static deformation analysis and estimation of wall stress distribution of patient-specific cerebral aneurysms can provide useful insights into the disease process and rupture. Method of Approach. The three-dimensional geometry...

... of w ) , the results are more easily visualized via standard stress-stretch type plots. In particular, equibiaxial stretching reveals well the multiaxial behavior including anisotropy. Given F 2 D = diag [ λ , λ ] , the resulting T - λ plots can be reconstructed...

... sufficient radial strength to prop the diseased artery open. The presence of a stent can subject the artery to abnormally high stresses that can trigger adverse biologic responses culminating in restenosis. The primary aim of this investigation was to investigate the effects of varying stent “design...
