Journal ArticleDOI
Fatigue life assessment of aluminum alloys with casting defects
TL;DR: In this article, the fatigue lifetimes of cylindrical aluminum specimens containing shrinkage cavities were measured and compared with those of specimens without macroscopic cavities (DC cast).
Journal ArticleDOI
Transversely isotropic membrane shells with application to mitral valve mechanics. constitutive modelling and finite element implementation
TL;DR: In this paper, the authors present constitutive modelling and implementation of transversely isotropic hyperelastic material models for the analysis of the mitral valve, which separates the left atri...
Journal ArticleDOI
On modelling and analysis of healthy and pathological human mitral valves: two case studies
TL;DR: The analyses showed that during systole the mitral valve from the HOCM heart bulged into the left atrium by taking on the shape of a balloon, whereas the anterior leaflet of the healthy valve remained in the left ventricle.
Journal ArticleDOI
Surface roughness characterization for fatigue life predictions using finite element analysis
TL;DR: In this paper, a finite element model of surface topography is proposed, in which microscopic surface measurements are used to create finite element models and the influence of surface roughness on fatigue life can then be based on stress solutions instead of empirically derived reduction factors.
Journal ArticleDOI
Finite element analysis of the mitral apparatus: annulus shape effect and chordal force distribution
TL;DR: The results show that the maximum principle stresses in the anterior leaflet are carried by the collagen fibers, and the stresses calculated in the leaflets are very sensitive to the thickness employed.
