The motion property of particles obeys Newton's second law of motion [45]. The relative position between particles changes as particles move, and the contact property changes accordingly. The variation of contact property satisfies the force–displacement law. ... Meanwhile, the effects of coarse aggregate crushing on concrete with different ...

The novelty of this model lies in the energy-based constitutive laws, which can describe the nonlinear phenomena involved in concrete cracking and crushing, together with their size-scale effects. In the present work, a scale effect on maximum reinforcement percentage, ρ max, is found proportional to h −0.25, being h the beam depth.
