When the cohesive zone length is of the order of the specimen size, the influence method — based on finite elements — may be used to solve the fracture problem. Here a brief outline of an enhanced algorithm for this method is given. For very large specimen sizes, an asymptotic analysis devel

These two aspects are combined in a continuous damage model. The

The structural response generally depends on both such numbers and, therefore, is not physically simi

Discussions concerning the application of the finite element method to crack initiation problems and the use of the size effect to estimate failure conditions in large, plain concrete structures are also presented.

When the specimen size is extrapolated to infinity, the fracture energy according to the RILEM recommendation coincides with the fracture energy obtained by the size effect method. It is also found that, in fracture specimens of
