Novel biaxial tensile test for studying aortic failure phenomena at a microscopic level [PDF]

BioMedical Engineering OnLine, 2013
Background An aortic aneurysm is a local dilation of the aorta, which tends to expand and often results in a fatal rupture. Although larger aneurysms have a greater risk of rupture, some small aneurysms also rupture. Since the mechanism of aortic rupture

Development of biaxial tensile testing for porous polymer membranes

Polymer Testing, 2022
Porous polymer membranes are typically polymeric materials that consist of many pores and complex network structures. As a result of these features, the membranes sometimes undergo anisotropic elastoplastic deformation. Hence, it is important to investigate the deformation behavior of these materials, including anisotropic deformation under multiaxial ...

Viscoelastic Properties of Porcine Pericardium Under Biaxial Tensile Creep and Stress Relaxation: Application for Novel Aortic Valve Bioprosthesis Design [PDF]

Bioengineering
To design novel heart valve bioprostheses, it is extremely important to predict leaflet failure and fatigue for 10–20 years, as the aortic valve opens and closes approximately 40 million times per year.

Numerical optimization-based design studies on biaxial tensile tests

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2023
Biaxial tensile tests are of great significance for the characterization of materials. For ductile materials, they allow the representation of the yield strength curve separating elastic and plastic material behavior. Contrary demands regarding the specimen design arise, if a biaxial stress state with the equivalent stress equal or close to the yield ...

Biaxial tensile testing of cruciform slim superalloy at elevated temperatures

Materials and Design, 2016
Abstract The stress–strain curves and yield loci of metallic materials under biaxial tensile tests can be precisely predicted using a yield criterion. In this study, biaxial tensile testing equipment with high-accuracy displacement, temperature control, and digital speckle correlation method of non-contact optical strain measurement is developed to ...

Biaxial tensile testing and constitutive modeling of human supraspinatus tendon [PDF]

2012 38th Annual Northeast Bioengineering Conference (NEBEC), 2012
The heterogeneous composition and mechanical properties of the supraspinatus tendon offer an opportunity for studying the structure-function relationships of fibrous musculoskeletal connective tissues. Previous uniaxial testing has demonstrated a correlation between the collagen fiber angle distribution and tendon mechanics in response to tensile ...
