## Description

- description: Van der Waals (vdW) materials consisting of two-dimensional (2D) building
    blocks have strong in-plane covalent bonding and weak interlayer interactions.
    While monolayer 2D materials exhibit impressive fracture resistance, as demonstrated
    in hexagonal boron nitride (h-BN), preserving these remarkable properties in vdW
    materials remains a challenge. Here we reveal an anomalous mechanical interlayer
    coupling that involves interlayer-friction toughening and edge-reconstruction
    embrittlement during the fracture of multilayer h-BN. Both asynchronous and synchronous
    fracture modes and their flaw-size dependence are identified. Edge reconstruction
    in the synchronous fracture mode can eliminate a toughening mechanism induced
    by lattice asymmetry in monolayer h-BN, leading to embrittlement of the multilayer
    h-BN, while the asynchronous fracture mode results in greater fracture resistance.
    Such findings will provide fundamental guidelines for engineering interlayer interactions
    in vdW materials including heterostructures and layered architectures for better
    mechanical and functional performances.
