Abstract
The dislocation contribution to the modulus defect ƊG/G has been found to be temperature dependent. It is shown that a temperature dependent modulus defect in reasonable agreement with experiment can be obtained by calculating the thermally averaged displacement [MATH] for a string model with Cottrell pinning point interactions using classical statistical mechanics.
