Estimating the material properties of heel pad sub-layers using inverse Finite Element Analysis

Process of Estimating the Material Properties of Human Heel Pad Sub- Layers Using Inverse Finite Element Analysis and Some Model Applications

A three-dimensional inverse finite element analysis of the heel pad.

Quantification of plantar tissue behavior of the heel pad is essential in developing computational models for predictive analysis of preventive treatment options such as footwear for patients with diabetes. Simulation based studies in the past have generally adopted heel pad properties from the literature, in return using heel-specific geometry with material properties of a different heel. In e...

Material properties of the heel fat pad across strain rates

The complex structural and material behaviour of the human heel fat pad determines the transmission of plantar loading to the lower limb across a wide range of loading scenarios; from locomotion to injurious incidents. The aim of this study was to quantify the hyper-viscoelastic material properties of the human heel fat pad across strains and strain rates. An inverse finite element (FE) optimis...

Material properties of the ovine mitral valve anterior leaflet in vivo from inverse finite element analysis.

We measured leaflet displacements and used inverse finite-element analysis to define, for the first time, the material properties of mitral valve (MV) leaflets in vivo. Sixteen miniature radiopaque markers were sewn to the MV annulus, 16 to the anterior MV leaflet, and 1 on each papillary muscle tip in 17 sheep. Four-dimensional coordinates were obtained from biplane videofluoroscopic marker im...

In Vivo Patient-specific Material Properties of the Subcalcaneal Fat: an Inverse Finite Element Analysis

Subcalcaneal fat serves as shock absorber and provides cushioning to the underlying foot structures and the body as a whole. Changes in mechanical response of the subcalcaneal fat (i.e., stiffening due to age [1] or diabetes [2]) can compromise the ability to dissipate plantar stress and potentially cause tissue injury. Inverse finite element (FE) analysis has been used to quantify mechanical p...
