Stability Index of Surrounding Rock during Deep Rock Excavation Considering Energy Release Speed
Rockburst is a kind of dynamic rock failure process that is easily induced by the excavation of a high-stress rock mass. However, from an energy perspective, the existing indexes for rockburst tendency have a limitation in that they do not consider the ...

Energy release rate for cracks in finite‐strain elasticity
AbstractGriffith's fracture criterion describes in a quasistatic setting whether or not a pre‐existing crack in an elastic body is stationary for given external forces. In terms of the energy release rate (ERR), which is the derivative of the deformation energy of the body with respect to a virtual crack extension, this criterion reads: if the ERR is ...

Research on Energy Dissipation Laws of Coal Crushing under the Impact Loads
Dynamic crushing characteristics of coals are closely related with energy absorption and release of coals under certain strain rate. Hence, it is necessary to investigate energy dissipation laws of coal crushing under the impact loads with different ...

Delamination Fracture Analyses of Linear-Elastic Functionally Graded Beams
An analytical approach for investigation of delamination cracks in three-dimensional functionally graded linear-elastic beams was developed. Beams which are functionally graded along their width, height and length were analyzed.

The Effect of Delamination Between Layers in U-shaped Members Made of Functionally Graded Multilayered Viscoelastic Materials [PDF]
This theoretical work deals with delamination in U-shaped load-carrying structural members. The latter represent multilayered functionally graded systems of non-linear viscoelastic behaviour.
