摘要: AbstractIn this paper, the development of a multiscale model collagen fibril is described using hierarchical approach by combining molecular dynamics simulations and FEM. Steered was used to investigate mechanical response under various conditions that mimic organization molecules mineral inside fibril. The steered showed elastic properties are significantly higher in proximity mineral. interfaces at scale were carried over continuum (measuring approximately 1 μm length 50 nm diameter) constructed Results deformation influenced interactions between scale, affecting Here, fibr...
