水泥净浆微观结构断裂破坏过程的三维模拟(英文)

Abstract:

在微观层次上研究了水泥净浆的断裂破坏过程,提出了两种模拟水泥净浆微观结构断裂破坏过程的方案,即格构模型HymLat方案和通用格构模型ImgLat方案。在HymLat方案中,被分析的水泥净浆微观结构只能是由球形颗粒组成,但在ImgLat方案中,研究对象不局限于由球形颗粒组成的微观结构,所有能由像素表达的微观结构都能采用ImgLat方案进行分析。这两种方案的共同之处是水泥净浆的微观结构均由HYMOSTRUC3D模型模拟得到,而断裂破坏过程都使用GLAK(GeneralizedLatticeAnalysisKernel)通用格构模型分析核心代码模拟仿真。对这两种方案在通用性和计算效率方面的差异进行了比较。
