Creep and Recovery of a Mineral Glass at Normal Temperatures

JSGT 1952 V36 T105-T114

Measurements have been made of the creep and recovery of a soda–lime–silica glass over the temperature range 20–80°C. The deformation of the glass can be divided into three parts:1. An instantaneous elastic strain; 2.A Newtonian viscous flow at constant rate, which is not recoverable. 3. A delayed elastic strain which develops slowly according to a decay function of time and which is completely recoverable.
