If aliens sent an exploratory mission to Earth, one of the first things they’d notice — after the fluffy white clouds and blue oceans of our water world — would be the way vegetation grades from exube...
Eigenfrequency correction of Bloch-Floquet waves in a thin periodic bi-material strip with cracks lying on perfect and imperfect interfaces
Bloch-Floquet waves thin periodic bi-material strip Mathematical Physics
2011/9/23
Abstract: We analyse an asymptotic low-dimensional model of anti-plane shear in a thin bi-material strip containing a periodic array of interfacial cracks. Both ideal and non-ideal interfaces are cons...
Weight function in a bimaterial strip containing an interfacial crack and an imperfect interface. Application to Bloch-Floquet analysis in a thin inhomogeneous structure with cracks
Bloch-Floquet waves boundary layer crack imperfect interface weight function

Abstract: We define a weight function in a bi-material strip containing a semi-infinite crack and an imperfect interface and analyse a problem of anti-plane shear. We then present an asymptotic algori...
Giant strain-sensitivity of acoustic energy dissipation in solids containing dry and saturated cracks with wavy interfaces
strain-sensitivity solids containing dry and saturated cracks
2011/9/2
Mechanisms of acoustic energy dissipation in heterogeneous solids attract much attention in view of their importance for material characterization, nondestructive testing, and geophysics. Due to the ...
Micro-seismic precursory cracks prior to rock-fall on coastal chalk cliffs:a case study at Mesnil-Val,Normandie,NW France
Micro-seismic precursory cracks rock-fall coastal chalk cliffs
2009/12/8
Erosion of rock cliffs has been considered to be relatively unpredictable. This perceived stochastic nature of the erosional processes often occurs through collapses along fractures in the rock-mass. ...
31 January 2007，Many insects’ wings are a special flexible shape to increase thrust and fly efficiently, engineers have found. This shape allows them to produce the vortices – spinning masses of air –...
Transition of mode II cracks from sub-Rayleigh to intersonic speeds in the presence of favorable heterogeneity
Dynamic fracture Supershear transition of earthquakes Crack mechanics Elastic material Boundary integral equations
2014/4/8
Understanding sub-Rayleigh-to-intersonic transition of mode II cracks is a fundamental problem in fracture mechanics with important practical implications for earthquake dynamics and seismic radiation...
