断裂力学应用于金属材料已取得了很大的成功,人们自然联想到是否能将断裂力学应用于混凝土一类的非金属材料。自从M.F.Kaplan于1961年首先将线弹性断裂力学的概念和方法应用于混凝土以来,国内外均已进行了很多研究,取得了一定的成果。混凝土是一种由骨料、水泥砂浆等所
The application of fracture mechanics to metal materials has been a great success, and people naturally think whether they can apply fracture mechanics to a class of non-metallic materials such as concrete. Since M.F. Kaplan first applied the concept and method of linear elastic fracture mechanics to concrete in 1961, many studies have been conducted both at home and abroad, and certain results have been achieved. Concrete is a kind of aggregate, cement mortar, etc.
