摘要:
为研究动荷载下平行双缝倾角变化对混凝土圆盘的影响,基于有限元方法,建立平台巴西圆盘的三维动态数值模型.采用Weibull统计学理论,考虑混凝土材料的非均匀分布,研究应力波作用下平行双缝倾角变化对裂纹扩展模式的影响,得到裂纹萌生、扩展直至贯通的破坏全过程图与声发射图.结果表明,试件的破坏是劈裂性的,新生裂纹扩展的方向与动荷载加载方向一致;声发射活动随预制裂纹倾角增大而减少;双缝预制裂纹倾角越大,峰值荷载越大,声发射累积能量越小,试件越不容易发生破坏.
Abstract:
In order to study the influence of the change of the inclination angle of parallel double slits on concrete disk under dynamic load, we establish a three-dimensional dynamic numerical model of the flattened Brazilian disc by using finite element method. Non-uniform distribution of concrete materials has been realized in the model by adopting Weibull statistical theory. Moreover, we study the effect of variation of dip angle of parallel double slits on crack propagation pattern under stress wave, and obtain both diagrams of the complete failure process and acoustic emission of crack initiation, propagation and penetration. The results show that the failure of the specimen is cleavage and the direction of new crack growth is consistent with that of the dynamic load, the acoustic emission activity decreases with the increase of the dip angle of the prefabricated slits; the bigger the dip angle of prefabricated parallel double slits is, the bigger the peak load is, and the less the accumulated energy of acoustic emission is, the less likely the specimen is to be damaged.
