Advanced Theory and Simulations, EarlyView.This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Far From Threshold Buckling Analysis of Thin Films
, 2010 Thin films buckle easily and form wrinkled states in regions of well defined size. The extent of a wrinkled region is typically assumed to reflect the zone of in-plane compressive stresses prior to buckling, but recent experiments on ultrathin sheets ...

Advanced Science, EarlyView.This study defines the structure, mechanics, and mechanobiology of the fibrocartilage pericellular matrix (PCM) using the murine meniscus, showing how collagen V deficiency alters PCM properties and disrupts cell mechanosensitive signaling. Findings emphasize the critical role of PCM in fibrocartilage mechanobiology and suggest targeting it can enhance
