Multiscale CAFE for fracture in heterogeneous materials under dynamic loading conditions
Abstract
This paper describes a multi-scale fracture framework, for modelling dynamic fracture in polycrystalline materials. The motivation behind developing such an application is to provide a high delity tool to model and capture dynamic structural deformations, at the macro scale, undergoing fracture at the micro-scale. The application links two highly scalable applications ParaFEM and CASUP, that model continuum using the finite element method and fracture using cellular automata respectively. Linking the two is done through a initial coupling step assigning the cellular automata to appropriate finite elements. Each time step the application passes data between the two packages, a stress tensor from ParaFEM to CASUP and a damage variable from CASUP to ParaFEM. If the maximum resolved normal stress on any cleavage plane exceeds fracture stress, crack propagation is induced through the material in the cellular automata, and the damage variable changes appropriately, updating the macro properties of the structure, modelled using finite elements. An example test case is shown, considering the degradation of a structure using material with differing critical stresses. The case showed materials undergoing permanent damage without failure and complete failure. Finally the parallel scalability of the application was explored and found to scale to 1000's of cores. Improved fidelity from coupling multiple scales in simulations has a wide range of applications in energy, aerospace and naval industries.
