Abstract
Dynamic loads such as blasts or ballistic impacts induce
different fragmentation zones. A damage law is used to describe the
fragmentation coupled with a Drucker-Prager model accounting for confined
damage. Two limestones are characterised to simulate edge-on impacts that
allow for the identification of the friction angle of the Drucker-Prager
model to avoid complex triaxial tests.
