Crack nucleation and propagation in rounded cohesive granular media
This work investigates the influence of cohesion on aspects of fracture mode and propagation in 2D rounded cohesive granular packing. Simulations are undertaken using the molecular dynamics method involving simple contact laws with adhesion. The numerical "Brazilian" test with samples of 8...

This work investigates the influence of cohesion on aspects of fracture mode and propagation in 2D rounded cohesive granular packing.

The agglomerate size is increased when the surface energy increases.
