The crack closure phenomenon significantly influences low cycle fatigue (LCF) crack growth. The crack closure theory deems that a crack can grow only when the applied load is greater than the fatigue crack opening and closing loads. The revised crack clo...

The use of energy fluxes data to validate land surface models requires that energy balance closure conservationis satisfied, but usually this condition is not verified when the available energy is bigger than the sumof turbulent vertical fluxes. In this ...

Firm birth and firm closure are two interrelated dynamics relevant to measuring economic growth, yet most studies focus on firm birth only. Public transportation infrastructure may facilitate firm birth, but it may also avert firm closure through improve...

River mouths are dynamic systems that can respond rapidly to both fluxes in fluvial water and sediment discharge and marine energy conditions, notably waves. On semi-arid wave-exposed coasts, the morphosedimentary behaviour of river mouths is particularl...

Many studies have shown that the linear elastic fracture mechanics (LEFM) method based on the stress intensity factor range (?K) has limitations that cannot be ignored. Due to neglecting the influence of plastic deformation near the crack tip, LEFM shows...
