and the bulge tests, with different alloys, such as copper, brass, aluminum and steel alloys, and compared the experimental findings with the corresponding stress-strain curve obtained from the tensile... it was easier to approach the best combination of the parameters. The strain rate range relevant to the tensile and compression tests was obtained from the numerical simulations. The stress-strain curves......
. For this purpose, pellets of activated carbon were prepared using pre-heated KBr in powder form. Activated carbon prepared was well mixed with KBr with the help of mortar and pestle. The mixture.... These functional group can act as an active site for the attachment of pesticide. It identified the change in bonds before and after the transformation of the activated carbon. The C-Br bending peak......

intermediate principal stress before the unloading, more elastic strain energy was accumulated in the specimen, and the cumulative AE energy was higher in the rockburst-induced failure, i.e., more elastic strain energy was released during the failure. Therefore, more violent failure was observed: more rock fragments with a higher mass and larger size were ejected outward. Key words: strainburst......
