摘要
COMSOL Multiphysics是一款专注于多场耦合的大型有限元分析软件,已经用于多个领域。由于混凝土结构多数情况是受多重因素的耦合作用,因此对复杂环境中的混凝土耐久性进行模拟时,COMSOL Multiphysics软件具有独特的优势。总结了COMSOL Multiphysics软件在混凝土的氯离子传输、碳化反应、冻融破坏、服役寿命预测等耐久性研究及其与XCT技术相结合建立几何模型中的应用现状,并对其在混凝土耐久性研究中的应用前景给予了展望。
COMSOL Multiphysics is a large scale finite element analysis software for multi-field coupling. It has been used in many fields. Since most of concretes are affected by multiple factors, COMSOL Multiphysics has a unique advantage in the simulation of the concrete durability. The applications of COMSOL Multiphysics in the research of chloride corrosion, carbonation reaction, freeze-thaw damage, service life prediction of concrete were summarized. In addition, the prospect of its application in the durability of concrete materials was also given.
