Abstract

Modeling fracture process in concrete has not given so far exact and unique solution. There are three common theories used to describe the fracture phenomenon in concrete: fracture mechanics, theory of plasticity and continues damage mechanics. However, regardless which of this theory is applied, they are faced with many problems, but four of them are pointed out in the paper as the most disputable. Yet, author's intention was not to discourage but it is aimed to focus researching attention to the key points in fracture analysis of concrete.
