混凝土构件软化分析的边界元法

BOUNDARY ELEMENT METHOD OF SOFTENING ANALYSIS FOR CONCRETE MATERIALS AND STRUCTURES

摘要: 本文在混凝土构件的软化分析中采用了粘性裂纹模型,使用直接边界元子域法研究并讨论了构件中裂纹开展所引起的结构软化和失稳情形,相应的增量迭代算法被给出。文中的数值算例表明了上述方法的有效性。

Abstract: In this paper the concrete material is considered as linear-elastic and isotropic but the fracture process is modelled according to the cohesive-softening crack idealization. A direct, collocation, multidomain boundary element method is employed and shown to be computationally effectivein the softening analysis. Sompe unmerical results were given and discussed.
