摘要
利用数字散斑相关方法,研究了混凝土试块在压缩载荷作用下的表面变形情况,绘制了混凝土试块表面x方向和y方向的位移场图。实验表明,数字散斑相关方法能够有效测定混凝土表面的变形分布情况,为进一步讨论混凝土材料的本构关系提供基础。
Using digital speckles correlation method,this paper researches concrete test cube surface deformation under compressive loading,and draws the full-field displacement map of x direction and y direction on concrete test cube surface.The experiment indicates that digital speckle correlation method can effectively test deformation distribution on the concrete surface.The experiment provides the underlying basis for further analysis of the constitutive relation on the concrete materials.
