1. State-of-the-art polymer shaping processes

Our focus is on the processing of thermoplastic polymers, whether or not reinforced with fillers or discontinuous fibers, i.e. materials to which the concepts of continuum mechanics can be applied on a macroscopic scale. Thermoset polymers and elastomers are therefore excluded from this analysis, even if some of the approaches we are developing are applicable to them.

Most of today's processing techniques (single or twin-screw extrusion, injection molding, hollow-body blow molding, film extrusion blow molding, calendering, etc.) were developed after the Second World War, at the same time as the development of the major commodity polymers. Some of these techniques were derived from related industrial sectors (food processing or rubber processing).

Since the 1950s, these processes have undergone continuous...
