A Micropolar Peridynamic Differential Operator and Simulation of Crack Propagation: 点击次数：; 所属单位： Department of Engineering Mechanics, Wuhan University; 发表刊物： Engineering Fracture Mechanics; 刊物所在地： ENGLAND; 摘要： The micropolar continuum explains the size effects in the materials with microstructures by attaching micro-rotations to the material points, but it still encounters difficulties when describing discontinuities. The peridynamic theory takes its advantage in dealing with discontinuous problems. This work formulates the micropolar continuum under the peridynamic differential operator framework. The micropolar elasticity field equations with spatial derivatives are rewritten in the spatial integral form such that the discontinuities can be naturally embedded in the micropolar continuum body.
