这篇论文论述调查纤维的裂缝开始性质的一个材料测试节目的数字分析围着确定的面板(RDP ) 的增强的水泥(FRC ) 。这研究的目的是设置一个修改 RDP 测试方法为 FRC 改进当前的 ASTM C1550 测试方法,纤维增强射击克利特岛(皇家学会会员) 合成。由这个测试方法,一种轻小直径的面板被使用,更多的裂缝信息能被测量技术的一个新旋转角度获得。这个修改测试方法能被用来有效地评估 FRC 的裂缝开始电阻,这被显示出。有限元素分析然后被执行澄清裂缝繁殖和 FRC RDP 面板的失败模式。它帮助建立一个合理理论方法预言 RDP 的结构的反应,与这种修改严峻的技术结合。
This paper presents a numerical analysis of a material test program investigating the crack opening properties of fibre reinforced concrete (FRC) round determinate panels (RDP). The objective of this research is to set up a modified RDP test method to improve the current ASTM C1550 test method for FRC and fibre reinforced shotcrete (FRS) composite. By this test method, light small-diameter panels are applied and more crack information can be obtained by a new rotation angle measuring technique. It is shown that this modified test method can be used to effectively evaluate the crack opening resistance of FRC. The finite element analysis was then performed to clarify the crack propaga- tions and failure mode of FRC RDP panels. It helps establish a reasonable theoretical method to predict the structural response of RDP. combining with this modified testing technioue.
