Fatigue crack behaviour: comparing three-point bend test and wedge splitting test data on vibrated concrete using Paris' law [PDF]
Fracture and Structural Integrity, 2017 The fatigue behaviour of concrete has become more important for the design of constructions due to the desire to build slimmer structures, which are more sensitive to fatigue loading.
