Mechanical analysis of a shear-cracked RC beam
Shear crack analysis is essential for engineers to estimate repair work in concrete structures. So far, conventional theoretical and numerical analyses in fracture mechanics have been applied to study concrete flexural beams, but there is still little ...

Crack nucleation in circular disk under mixed boundary conditions
A model of crack nucleation in a circular disk, based on consideration of cracking process zone is suggested. It is assumed that the cracking process zone is a finitelength layer containing a material with partially disturbed bonds between separate ...

Dynamic nucleation as a cascade-up of earthquakes depending on rupture propagation velocity
Earthquake dynamic rupture requires a nucleation process to provide sufficient energy to overcome the fracture energy. Large earthquakes may occur via a cascading rupture process, which includes many triggering processes that cascade from small to large ...
