Abstract

We show that broken bonds can act as negative stiffness elements, but during a very short time. If at the time of bond breakage the geomaterial was in an almost incompressible state due to for instance dilatancy in compression, the breakage leads to material instability that starts at the peak stress. © Springer International Publishing AG 2017.
