Mongrain, and J. C. Tardif<br/> The comparison, evaluation, and optimization of new techniques, models, or algorithms often require the use of realistic deformable test phantoms. The purpose of this paper is to present a multilayer deformable test specimen mimicking an atherosclerotic coronary artery, suitable for mechanical testi ... [J. Biomech.

Mixed Experimental and Numerical Approach for Characterizing the Biomechanical Response of the Human Leg Under Elastic Compression http://link.aip.org/link/doi/10.1115/1.4000967 Stephane Avril, Laura Bouten, Laura Dubuis, Sylvain Drapier, and Jean-Francois Pouget<br/> Elastic compression is the process of applying an elastic garment around the leg, supposedly for enhancing the venous flow. However, the response of internal tissues to the external pressure is still partially unknown. In order to improve the scientific knowledge about this topic, a slice of a human ... [J. Biomech.

Chaves, and Ch. Brucker<br/> The convective transport of fluid within the human upper airways is investigated in a transparent model of the tracheobronchial tree. Oscillatory flow through the branching network with six generations was studied at varying Reynolds numbers between 400 and 2600 and Womersley numbers from 5.5 to 12. ... [J. Biomech.

Strain Measurement of Pure Titanium Covered With Soft Tissue Using X-Ray Diffraction http://link.aip.org/link/doi/10.1115/1.4000935 Kazuhiro Fujisaki and Shigeru Tadano<br/> Measurement of the stress and strain applied to implants and bone tissue in the human body are important for fracture prediction and evaluations of implant adaptation. The strain of titanium (Ti) materials can be measuring by X-ray diffraction techniques. This study applied X-ray diffraction to the ... [J. Biomech.

Craig Dutton, and Bumsoo Han<br/> In order to cryopreserve functional engineered tissues (ETs), the microstructure of the extracellular matrix (ECM) should be maintained, as well as the cellular viability since the functionality is closely related to the ECM microstructure. Since the post-thaw ECM microstructure is determined by the ... [J. Biomech. Eng. 132, 031003 (2010)] published Thu Feb 4, 2010. Changes in Collagen With Aging Maintain Molecular Stability After Overload: Evidence From an In Vitro Tendon Model http://link.aip.org/link/doi/10.1115/1.4000933 Thomas L. Willett, Rosalind S. Labow, Ian G. Aldous, Nick C. Avery, and J. Michael Lee<br/> Soft tissue injuries are poorly understood at the molecular level. Previous work using differential scanning calorimetry (DSC) has shown that tendon collagen becomes less thermally stable with rupture. However, most soft tissue injuries do not result in complete tissue rupture but in damaging fiber ... [J. Biomech. Eng. 132, 031002 (2010)] published Wed Feb 3, 2010. Robust and General Method for Determining Surface Fluid Flow Boundary Conditions in Articular Cartilage Contact Mechanics Modeling http://link.aip.org/link/doi/10.1115/1.4000869 Sainath Shrikant Pawaskar, John Fisher, and Zhongmin Jin<br/> Contact detection in cartilage contact mechanics is an important feature of any analytical or computational modeling investigation when the biphasic nature of cartilage and the corresponding tribology are taken into account. The fluid flow boundary conditions will change based on whether the surface ... [J. Biomech. Eng. 132, 031001 (2010)] published Wed Feb 3, 2010.
