Damage analysis four-point bending fatigue tests on stone matrix asphalt using dissipated energy approaches

, 2020
Four-point bending tests under strain-controlled mode were conducted on a stone matrix asphalt. Fatigue properties were evaluated by comparing indexes and fatigue curves at different frequencies, temperatures, and strain levels.

Laboratory investigation of fatigue parameters characteristics of aging asphalt mixtures: A dissipated energy approach

, 2020
The objective of this paper is to reveal the effects of aging on the fatigue performance of asphalt mixture based on variation patterns of fatigue parameters with aging degrees. Specimens with different aging degrees were prepared by modified SHRP’s Long-

Expressions of stored and dissipated energy densities

, 2020
There exist several unequivalent expressions of stored and dissipated energy densities. It is still lack of correctness judgement for these expressions. Here, we shall propose that the time-averaged form of Poynting’s theorem, which implies that the net ...

A Hierarchical Energy Dissipated Structure Enabled Strong, Ultra‐Tough, and Sustainable Adhesives

Advanced Functional Materials
Sustainable adhesives with simultaneous high strength and excellent ductility are important but still challenging. Here, an epoxy adhesive with simultaneously strong, tough, and sustainable features by designing a new hierarchical energy‐dissipated cross‐

Experimental characterisation of fatigue damage in foamed bitumen stabilised materials using dissipated energy approach

Construction and Building Materials, 2019
Foamed bitumen stabilisation (FBS) of degraded pavements has become popular in recent times. Although the common failure mechanism of FBS materials under repeated heavy traffic loads has been identified as bottom-up fatigue cracking, further research is ...

Energy Dissipation in Dynamic Fracture

Physical Review Letters, 1996
Measurements in PMMA of both the energy flux into the tip of a moving crack and the total surface area created via the microbranching instability indicate that the instability is the main mechanism for energy dissipation by a moving crack in brittle, amorphous material. Beyond the instability onset, the rate of fracture surface creation is proportional
