To explore the dynamic characteristics and damage evolution laws of deep coal rock under impact loads, the dynamic load response laws of coal rock at different strain rates under high-frequency ...

When characterizing the strain rate sensitive deformation mechanics of materials, high strain rate testing is essential. Conventionally, in a standard nanoindentation test, a load is applied to the ...

Disc coal samples with different water content were tested using the split Hopkinson press bar test system. Their dynamic tensile failure process was monitored via an ultra-high-speed digital image ...

Hysitron nanoDMA III from Bruker is the latest powerful dynamic testing method to perform nanoscale mechanical property measurements. nanoDMA III is fitted with the recently developed CMX control ...
