摘要

利用ANSYS有限元软件建立细观层面上带有随机分布的玄武岩纤维

考虑纤维与混凝土界面粘结滑移的混凝土模型对抗压试验进行模拟

以考察玄武岩纤维在混凝土受力发生变形至开裂的过程中所起的作用及纤维的掺量对应力分布情况的影响。结果表明:直到材料发生塑性变形

纤维才开始分担受力

纤维掺量对应力应变关系的影响才开始凸显

混凝土发生开裂时

纤维体现了明显的阻裂效果;随着纤维掺量的增大

纤维对混凝土应力集中的分散效应逐渐增强。

Abstract

To investigate the effect of basalt fiber on the high performance concrete

in particular during the deformation and cracking process and how basalt fiber content affects the concrete stress distribution

a numerical simulation was performed using the finite element analysis software ANSYS.A model of concrete with randomly distributed basalt fibers was established on the mesoscopic level to simulate the compression test of composite materials.The result of analysis showed that the fiber started to share the stress on the substrate in the nonlinear stage

and the influence of fiber volume fraction on the stress-strain relationship became obvious.When the concrete cracked

the effect of fiber to resist the cracks was evident.Moreover

with the increase of fiber content

the effect of dispersion of fiber increased.
