Abstract
Based on the stress-strain curves of foam-concrete, a constitutive model to describe the process of pore collapse of porous material is proposed. The behavior of uniaxial strain wave propagated in foam-concrete was numerically simulated, and the attenuation effects of the peak stress and the peak energy of the stress waves were studied. The results show that the foam-concrete has strong capability to absorb the stress wave in the stage of pore collapse, and the factor caused by pore collapse is the most important and significant factor leading to the stress wave attenuation.
