Abstract
Uniaxial tensile tests of glass specimens were carried out at a range of strain rate and temperatures. The strain rate and temperature dependencies on the tensile strength (breaking stress) of the glass were investigated in detail. The relationship between tensile strength, strain rate and temperature can be expressed using exponential functions given by Norton's law and an Arrhenius type equation. An empirical equation expressing the temperature and strain rate dependencies of tensile strength was obtained from the experimental results. The strength of the glass was discussed from the standpoint of the thermo-viscoelastic properties of the material.
