Effect of Aggregate Gradation on Reducing Reflection Crack
Journal of Engineering and Sustainable Development, 2010 e rehabilitation of cracked flexible pavement roads by overlaying, without any improvement, is rarely a durable solution, as the cracks rapidly propagate through the new asphalt layer.

Propagation Law of Cracks in Surrounding Rock of Different Shape Tunnels Under Adjacent Blasting
Meikuang Anquan, 2020 To understand the effect of the tunnel section shape on the crack propagation law of surrounding rock in adjacent tunnel under blast loading, detailed research is carried out by model test and extended finite element(XFEM).

On the puzzling feature of the silence of precursory electromagnetic emissions [PDF]
, 2013 It has been suggested that fracture-induced MHz-kHz electromagnetic (EM) emissions, which emerge from a few days up to a few hours before the main seismic shock occurrence permit a real-time monitoring of the damage process during the last stages of ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Advanced Engineering Materials, EarlyView.This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites
Advanced Engineering Materials, EarlyView.Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

BuildingsCracks are the most typical faults of concrete structures, and their extension can lead to structural fracture. However, when cracks develop inside a structure, the most important depth information is invisible and difficult to measure.
