On the Dynamic Fragmentation of two Limestones using Edge-on Impact Tests
Résumé
Two limestones are studied to compare the fragmentation pattern induced by dy- namic loads. A quasi-static characterization allows one to determine the basic me- chanical properties and to compare the two rocks in terms of Weibull parameters, indicators of microstructural differences. Edge-on impacts are performed and show the important role of the Weibull modulus in the fragmentation pattern. Simula- tions of these experiments are performed and validate the simple model proposed for rocks.
