Temperature dependence of dynamic yield stress in amorphous polymers as indicator for the dynamic glass transition at negative pressure

The dynamic yield stress for polycarbonate, polystyrene and poly(methyl methacrylate) was measured by an instrumented Charpy impact tester in a wide temperature range. The dynamic yield stress is interpreted as being proportional to a negative pressure. The temperature dependence can be described by...
