We successfully applied the Bauwens approach to describe the behavior of the modified epoxy joint (0.5 mm thick joint) over a wide range of strain rates and temperatures.
Therefore, in the temperature range from 24 to 80 [degrees] C, the yield behavior of the modified epoxy joint, above [Mathematical Expression Omitted], may be described by the sum of the partial stresses [[Tau].sub.[Alpha]] and [[Tau].sub.[Beta]] required to free the different kinds of molecular motions implied in the deformation process.
It means that the yield behavior of the modified epoxy joint occurs for a same microstructural state in the corresponding temperature range.
So, Eq 8 clearly shows the agreement between the thermodynamic model of Escaig and the Eyring-Bauwens approach, to account for the behavior of the modified epoxy joint at high strain rates in terms of molecular motions linked to the [Beta] relaxation.
