The cross-crack means that the crack plane is vertical to the crack plane of the line-crack. The effective glass transition temperature of PMMAis reduced after the ethanol treatment. Both crack healings only occur at the effective glass transition temperature lower than the transport temperature. Both crack closure rates are constant. The closure rate of the cross-crack is higher than that of the line-crack. The analyses of the surface morphology and mechanical st
