摘要
利用 Griffith准则和断裂力学原理讨论了带缺口的素混凝土和纤维薄板增强混凝土三点弯曲梁试件的断裂扩展问题。初步分析表明 ,纤维增强混凝土缺口试件的开裂荷载比素混凝土缺口试件提高 2 3 .9% ,而失稳荷载比素混凝土缺口试件提高 112 .5 %。
With Griffith criterion and principle of fracture mechanics, a problem of the crack propagation of plain concrete and fiber sheet reinforced concrete 3-P bending specimen is discussed . The analysis shows that the cracking load of fibre reinforced concrete specimen with a notch is inereased by 23.9% and the rupture load is increased by 112.5% compared with that of plain concrete specimen with a notch.
