Mechanics fundamentally governs the way cells and tissues adopt their functional shapes, the way they resist stresses, and the way they move, individually or collectively. In turn, mechanical forces critically influence cell behavior. Over the last decade, the field of mechanobiology has emerged, emphasizing the tight interplay between mechanics and biological function.

The surface-forming energy release rate versus the local energy release rate

fracture mechanics

In our just published paper, we identify two ways to extract the energy (or power) flowing into a crack tip during propagation based on the power balance of areas enclosed by a stationary contour and a comoving contour. It is very interesting to find a contradiction that two corresponding energy release rates (ERRs), a surface-forming ERR and a local ERR, are different when stress singularity exists at a crack tip. Besides a rigorous mathematical interpretation, we deduce that the stress singularity leads to an accompanying kinetic energy at the crack tip.

Tropocollagen types I and III were simultaneously fibrilized in vitro, and the differences between the geometric and mechanical properties of the heterotypic fibrils with different mixing ratios of tropocollagen III to I were investigated. Transmission electron microscopy was used to confirm the simultaneous presence of both tropocollagen types within the heterotypic fibrils. The incorporation of collagen III in I caused the fibrils to be thinner with a shorter D-banding than pure collagen I.
