摘要

Based on the tensile feature and rupture mechanism, the point interpolation meshless algorithm of smeared crack model is proposed. When the displacement of crack opening and the fracture energy are smeared into the node influence area, the calculation results vary with the size of the node influence area which is called size effect. According to the conversation law of fracture energy, the solution of size effect of simulation of tensile crack process using the blunt crack band model is proposed and verified through a numerical test of concrete three-point bend beam.
