Numerical Analysis of Some Experimental Data concerning the Size Effects on Fracture Parameters

The existing experimental data concerning the Size Effects on the fracture parameters [1] were analyzed, in order to check the validity of certain theoretical models. In this aim, the present work studied: a) the use of some rigorous statistical tests in order to eliminate the “rough” errors, b) different theoretical models (e.g. the Bazant’s Size Effect Law (SEL) [2], the Modified Size Effect Law [3], [4], and the Carpinteri’s MultiFractal Scaling Law (MFSL) [5]) of the fracture parameters of concrete specimen, c) the compatibility of some of the above studied theoretical models relative to the experimental data, using certain recent procedures to study the global and local compatibility.
