基于近场动力学的泡沫水泥石破坏机制研究及抗压强度预测
Study on the damage mechanism of foam cement and prediction of compressive strength based on peridynamics
摘要
Abstract
To clarify the impact of a pore structure on the compressive strength of a cement stone,a numerical model of peridynamics for foam cement was established,and uniaxial compression simulations were conducted under different parameter conditions using Peridigm.The research shows that the damage inside foam cement expands from the thin-walled regions to the entire cement stone.The compressive strength of the foam cement is negatively correlated with porosity and pore size,and positively correlated with pore sphericity.A prediction model for the compressive strength was established based onover 2,900 models,providing a theoretical basis for the rational design of foam cement to meet different strength requirements.关键词
