title = "Dynamic fracture simulation of flexible multibody systems via Absolute Nodal Coordinate Formulation and SPH method",
abstract = "A new computation methodology is proposed to study the dynamic fracture process of flexible multibody systems with initial cracks. The potential fracture domains of flexible parts are described by using the Smoothed Particle Hydrodynamics (SPH) method, and the other domains are represented by using the Absolute Nodal Coordinate Formulation (ANCF). The interaction forces between the SPH particles and the ANCF elements are transmitted by the virtual particles. The GPU based OpenACC parallel technique is used to improve the efficiency of interaction detection for SPH particles. A predictor-corrector scheme is used to solve the SPH particles governing equations, while the generalized-alpha method is used to solve the huge set of Differential Algebraic Equations (DAEs) of the ANCF elements. The OpenMP parallel technology is also employed to efficiently evaluate the element elastic forces and their Jacobians. Finally, a numerical example is given to validate the proposed computation methodology.",
