抗裂圆环的干缩应力分析Ⅱ.均匀干燥时水泥基材料弹性模量的影响

Shrinkage Stress Analyses on Breaking Ring——Ⅱ. Effecting on Elastic Modulus of Cementing Materials During Homogeneously Drying Process

根据弹性力学基本方程,研究了均匀干燥过程中水泥基材料弹性模量对径向位移分布、径向应变分布、环向应变分布、径向应力分布和环向应力分布的影响,分析了其机理,探讨了圆环抗裂试验方法定量化的途径。

According to the equations of elasticity, the influences of the elastic modulus of cementing material on the distribution of the radial displacement, radial strain, circumferential strain, radial stress and circumferential stress in ho-mogeneously drying process are studied, and the mechanism is analyzed. The way of quantitative analysis for the test method of breaking ring is discussed.
