摘要
采用数字图像相关方法(DICM)研究了在疲劳荷载作用下混凝土表面的位移场及应变场分布,并着重分析了混凝土在裂缝出现前后的位移、应变变化。试验结果表明,数字图像相关方法具有可行性,能够有效地测量混凝土在疲劳荷载作用下的位移和应变。
Digital image correlation method（DICM）was used to investigate the full-field displacement and strain distribution in concrete tinder fatigue loading, emphatically analyzed the displacement and strain when the concrete crack appeared. Test results demonstrated that digital image correlation method was effective, which could precisely measure the displacement and strain distribution in concrete under fatigue loading.
