Size Effect in Brazilian Split-Cylinder Tests: Measurements and Fracture Analysis
TL;DR: In this article, the size effect in the split cylinder tensile test is studied experimentally and analyzed theoretically, and the results confirm the existence of size effect and show that up to a certain critical diameter d, the curve of nominal strength versus diameter approximately agrees with the law proposed by Bazant for the size effects caused by energy release due to fracture growth.

Fracture mechanics and size effect of concrete in tension
TL;DR: In this article, it was found that strength of concrete structures generally decreases with increasing structure size before reaching a limiting value, and Fracture mechanics was used to predict such size effect.

Effects of Load-Distributed Width on Split Tension of Unnotched and Notched Cylindrical Specimens
TL;DR: In this article, the effect of load-distributed width on maximum tensile stress in unnotched and notched cylinders in split tension has been analyzed based on finite element analysis, and linear elastic fracture mechanics (LEFM) formulas for the stress intensity factor KI, crack mouth opening displacement (CMOD), and the crack opening displacement profile for the split tension of notched cylindrical cylinders were provided in terms of load distribution.

Direct determination of weight functions from reference loading cases and geometrical conditions
TL;DR: In this article, a procedure is discussed that allows the determination of weight functions from a number of known reference stress intensity factors and two geometrical conditions, namely vanishing second and third derivatives of the weight function (h'' = h''' = 0 ) at the crack mouth.

Determination of the fracture parameters of the Double-K model using weight functions of split-tension specimens
TL;DR: In this paper, splitting tests on cubical, cylindrical and diagonal cubic concrete samples were analyzed to determine the fracture parameters for the Double-K model and the universal four-term weight functions of these specimens were determined.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.
