Experimental Investigation of Subcutaneous Pressure and Shear Force Changes Using a Bone Protrusion Model as a Risk Factor for Pressure Ulcer Development [PDF]

open access: yesJournal of Plastic and Reconstructive Surgery, 2023
Objectives: Subcutaneous pressure and subcutaneous shear force were investigated using a bone protrusion model to investigate a polyurethane film dressing (hereinafter referred to as adhesive film) for preventing shear force. Our hypothesis was that when

Exploring shear-induced segregation in controlled-velocity granular flows [PDF]

open access: yesEPJ Web of Conferences, 2021
Particle segregation in geophysical and industrial granular flows is typically driven by gravity and shear. While gravity-induced segregation is relatively well understood, shear-induced segregation is not. In particular, what controls segregation in the

Brownian Forces in Sheared Granular Matter [PDF]

open access: yesPhysical Review Letters, 2006
We present results from a series of experiments on a granular medium sheared in a Couette geometry and show that their statistical properties can be computed in a quantitative way from the assumption that the resultant from the set of forces acting in the system performs a Brownian motion.

Numerical Analysis of Dead Load Shear Force Distribution in Webs of Multicell Inclined Web Box-Girder Bridge

open access: yesAdvances in Civil Engineering, 2020
Moment and shear load distribution are important in bridge design. Most existing studies have focused on the distribution of girders under vehicle loading, neglecting the dead load distribution between the webs of multicell box-girders.
