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.

Study of the Impact Energy Releasing Characteristics of Al/PTFE/W Energetic Jets
Compared with traditional jets, energetic jets have more efficient damage effects. To study the reaction characteristics of polytetrafluoroethylene- (PTFE-) based energetic jets under impact loading, the static mechanical properties of Al/PTFE/W ...
