摘要：

The compression yield stress behaviour of engineering polycarbonates in the glassy state has been investigated over a wide range of strain rates (10-4-4500 sec-1) and temperatures (-40 to 60°). In this region, the Ree-Erying and Bauwens approach takes into account a distribution of two different relaxation times (α and β). At high strain rate in the glassy range, this model provides evidence on the secondary transition linking the yield behaviour with the β mechanical loss peak. © 1990.
