WebJan 10, 2024 · High wall shear stress (WSS) has recently been proposed as one possible causative factor, promoting the development of high-risk plaques. High WSS has been shown to induce specific changes in endothelial cell behavior, exacerbating inflammation and stimulating progression of the atherosclerotic lipid core. Webdepends on how you look at it. either way, friction would oppose the force pushing the material, which is why the bend is not instantaneous. The way that he shows shearing is true if the force pushing the material is constant. if the force is instantaneous however,then because of friction, it will not bend as far before bouncing back.
