Fracture Characteristics of Asphalt Concrete in Mode I, Mode II, and Mixed-Mode
… Mixed-Mode testing of asphalt concrete, but only Crack Mouth Opening Displacement (CMOD) was used. This research captured the Crack Tip Opening Displacement (CTOD) and Crack Tip Sliding Displacement (CTSD) in addition to CMOD. This allowed the comparison of three different values of fracture …

Simulation of Fracture of Concrete Using Micropolar Peridynamics
… by the bilinear cohesive model in the cohesive crack approach, a new constitutive damage model is proposed to simulate the tensile fracture of a normal-strength concrete. Laboratory experimental data for crack mouth opening displacement vs. load of notched beams, obtained by Chapman in 2011 …

Cohesive zone modeling of fracture of sustainable and functionally graded concrete
… relationships defined along the crack surface, are utilized to simulate mode I fracture of the slabs. Based on the load to crack mouth opening displacement (CMOD) relationships of the slab, one is able to optimize concrete properties and placement to reach predefined goals. A …

Numerical Modelling of Steel Fibre Reinforced Concrete Subjected to Fatigue Loading
… tension and thus susceptible to the formation of cracks when under tensile stresses. Steel Fibre Reinforced Concrete (SFRC) improves post-cracking behaviour through enhanced tensile strength, toughness, and crack control, offering increased resistance to fatigue damage. Despite extensive …

Displacement rate and temperature effect on asphalt concrete cracking potential
… concrete (AC) in flexible pavements is thermal cracking alongside fatigue, weathering related cracking and rutting. Pavements in Illinois road network are highly prone to different sources of cracking because of the climatic conditions and heavy traffic loads. Daily temperature fluctuations and …
