报告摘要：In this talk, we will introduce an adaptive coupling approach of local and non-local micromechanics for predicting the microcrack propagation in composites. The special feature of this method is that it can take full advantages of both continuum micromechanics as a local model and peridynamic micromechanics as a non-local model to achieve composite fracture simulation with a higher level of accuracy and efficiency. These two models are coupled into a closed equation system, and a transition region is introduced to achieve a smooth transition between them. A composite strength-induced adaptive algorithm is introduced to solve the unified model. The micromechanics-based coupling method has the potential to efficiently simulate the microcrack propagation in various complex composite materials.
