Abstract

Deformation behavior of foaming glass was investigated and modeled for the purpose of establishing the methodology of forming. Waste glass powder with a foaming agent was compacted into cylindrical specimens and fired. The expansion and the shape change in the specimens were investigated. Deformation behavior of the foaming glass was described by a constitutive equation for a porous body. The gas pressure, evaluated from a rate equation for the reaction of the foaming agent and the equation of state with the temperature, was introduced into the constitutive equation as a hydrostatic stress acting on the inside of the body. Based on the developed constitutive equation, the deformation of the foaming glass was simulated by a coupled finite element method of deformation and heat transfer, taking into account the gravity and surface tension. The calculated shape change in the glass foam shows good agreement with that obtained from experiment.
