Abstract: In order to reveal the influence law of graphite ore grade on its dynamic mechanical properties, SHPB tests were carried out on graphite ore samples with five grades of 1.57%,5.19%,10.79%,12.65% and 19.50% under the action of constant amplitude impact loads.Based on the analysis of microscopic fabric characteristics of the graphite ore, the peak strength（σd）,dynamic elastic modulus（Ed）,peak strain（εd） and energy consumption density(ASE) of the samples ... More
