Advanced thermomechanical constitutive models for airfield concrete pavement under high temperatures
1998
An axisymmetric thermomechanical constitutive model is proposed for airfield concrete pavement under very rapid heating and cooling processes due to high-temperature exhaust gas from axisymmetric vectored thrust engines. Newman's crack growth model is applied to estimate the delamination (thermal spalling) time of the airfield concrete pavement at various locations due to the internal pore pressure. Furthermore, coupled heat and mass transfer in concrete pavement is considered.
