Instabilities in bilayered systems can generate a wide variety of patterns ranging from simple folds, wrinkles, and creases to complex checkerboards, hexagons, and herringbones. Physics-based theories traditionally model these systems as a ...
Rupture mechanics of blood clot fibrin fibers: A coarse-grained model study [0.03%]

Cells in solid tissues sense and respond to mechanical signals that are transmitted through extracellular matrix (ECM) over distances that are many times their size. This long-range force transmission is known to arise from strain-stiffenin...
Supershear surface waves reveal prestress and anisotropy of soft materials [0.03%]
超 shear 表面波揭示软材料的预应力和各向异性
