Study of mechanical effects of microfluidic channels in microneedles
… of the integrated microfluidic channels on the mechanical integrity of these probes. We have developed a set of tools to help us answer this question. We built an analytical model to predict the mechanical strength of a probe and used that backbone to answer the inverse question of what range of …

Mechanical Effects of Surgical Adhesives on Ascending Thoracic Aortic Aneurysm Replacement
… anastomotic site. This study aims to investigate mechanical effects of four commonly used surgical adhesives, namely BioGlue, CoSeal, Crosseal, and Tisseel, on the suture site using in-vitro digital image correlation (DIC) method and finite element (FE) simulations in an ovine model. In this …

Modeling the Mechanical Effects of Liquid Mediated Adhesion Between the Human Vocal Folds
The vocal folds are a complex self-oscillating biological system. In the current research, an equation was developed to model viscous adhesion forces that occur when the collision of the vocal folds results in the formation of a liquid bridge. The adhesion equation was validated using experimental …

A computational study of post-infarct mechanical effects of injected biomaterial into ischaemic myocardium
Cardiovascular diseases account for one third of all deaths worldwide, more than 33% of which are related to ischaemic heart disease, involving a myocardial infarction (MI). Emerging MI therapies involving biomaterial injections have shown some benefits; the underlying mechanisms of which remain …

Bench-scale modeling to evaluate the mechanical effects of subsidence on a monofill-type landfill cover
A bench-scale model was developed to simulate the effects of subsidence on compacted monofill-type landfill covers for the low-level radioactive waste landfills of the Radioactive Waste Management Sites of the Nevada Test Site. Of particular interest is the collapse mechanism of the cover with …

Synchrotron X-Ray Diffraction and Piezospectroscopy used for the Investigation of Individual Mechanical Effects from Environmental Contaminants and Oxide Layer Undulations in Thermal Barrier Coatings
… (CMAS). Previous studies have shown that these effects present themselves through variations in the thermomechanical and thermochemical properties of the coating. This study investigated the impact of CMAS ingression on the Yttria Stabilized Zirconia Topcoat (YSZ) and Thermally Grown Oxide (TGO) …
