| Abstract: | This paper presents a bond-based peridynamic (BBPD) model with rotational effects, accounting for the phonon-phason coupling to simulate damage evolution in one-dimensional hexagonal quasicrystals (1DHQCs) thin plate with a central crack. The expressions of the microscopic bond potential energy and the pairwise force are derived, from which the micromodulus functions are obtained. Based on these, a bond-based methodology is designed to simulate dynamic crack propagation while mitigating mesh sensitivity. The details are as follows: (i) the equations of motion are discretized; (ii) an explicit time-integration algorithm based on the central difference method is developed; (iii) a mesh adaptive strategy is introduced. Numerical results indicate that the phason field dissipates energy at the crack tip, thereby preventing local energy concentrations and delaying both crack initiation and branching. Furthermore, the reduction of shear stress in the phonon field alters the crack propagation mode from multidirectional branching to a straight path along the loading direction. These findings demonstrate the regulatory role of shear stress on crack morphology. The proposed BBPD method provides a novel pathway for investigating fracture in 1DHQCs, as it naturally captures crack propagation through bond-breaking without requiring a predefined path.
