crushing energy calculated

crushing energy calculated fondation-la-tene.ch
· The mean crushing force (F mean) for a given crushing distance d was calculated as: (2) F m e a n = E A d F mean is an important indicator to assess the crashworthiness of structures; a higher F mean can absorb more energy with a certain deformation.The relationships between particle size and fracture energy (strain energy) were calculated by using the results of the size effect ranging from about 10 em

Soil-Aggregate Crushing-Energy Meter, A USDA
2013-4-8 The energy was calculated from the Instron chart intwo different ways. First, the graph of force vs. displace-ment was cut out, weighed, and compared with the weightof a known area of the paper to obtain the energy rep-resented by the graph. The second method was to countthe chart paper divisions enclosed by the crushing curveand compare to the number of divisions in the standardarea. These two methods should give the same results towithin the accuracy of the cutting and counting.The break force and energy readings found by thesemethods were compared to the readings found bySACEM. The results of these comparisons are shown inFig. 3 through 5. In Fig. 3, the break force read fromthe Instron chart was plotted against the break force asdetermined by SACEM.
