Development of Mechanistic-Empirical Principles for Jointed Plain Concrete Pavement Fatigue Design
… bottom-up transverse, longitudinal, and corner cracking were found to be critical fatigue mechanisms depending on the pavement geometry, climatic zone, and material parameters selected. These results are in contrast to the assumed bottom-up, mid-slab transverse cracking mechanisms, which are …

Early Damage State Criterion from a Fault-Seeded Helicopter Gear Using Acoustic Emission and Neural Networks
… Professional II/Plus software to separate cracking signals from other mechanisms such as noise and plastic deformation. Visual inspection and statistical analysis of the data in the AE plots created using the output ANN results was used to separate the cluster(s) which exhibited higher …

Development of domain integral and generalized finite element methods for three dimensional analysis of near-surface cracking in flexible pavements
… in the analysis of classical bottom-up fatigue cracking of relatively thin flexible pavements, where tensile stresses and strains govern the behavior at the asphalt layer. However, elastic theories are incapable of predicting other pavement distresses, including near-surface cracking. Similarly, …

Structure, strength and defect characterisation of cement based materials.
… and lead to increased understanding of cracking mechanisms in concrete containing various types of additives and aggregates. The application of the AE technique allowed the failure of interfacial bonding to be observed. The variation of the aggregate size and its effect on the monitored …

Predicting microstructural heterogeneities in the laser powder bed fusion of γ′ strengthened nickel-base superalloys
… high γ′ content and hence, highly prone to weld-cracking. Multiple cracking mechanisms have been identified as active in the LPBF of various precipitation-strengthened superalloys. However, there is no precise understanding of how LPBF thermal processing conditions induce the development of …

Estudio experimental de la fisuración en piezas de hormigón armado sometidas a flexión pura
… behaviour of concrete. An understanding of cracking mechanisms in reinforced concrete structures is requisite to any analysis of their in-service performance, whether the focus is on durability, watertightness, aesthetics or the reduction of the psychological effect on users. Studies …

Investigation on the mechanisms of block cracking in asphalt pavements
Block cracking in asphalt pavements is a primary form of surface cracking but has been the subject of very few scientific investigations. The extensive nature of this cracking form often leads to significant maintenance costs and reduces the ride quality and service life of the pavement surface. …
