The mechanical behaviour of polymers is usually time-dependent, sometimes anisotropic, and is generally strongly influenced by their microstructure, which is formed during processing of synthetic polymers, and is also an important characteristic of biopolymers. The physical age of amorphous polymers depends on their thermomechanical history and morphological characteristics of semicrystalline polymers, such as the degree of crystallinity, and crystal type, size and orientation are determined by processing and ageing conditions. In short fibre-reinforced polymers, the fibre orientation distribution is formed in the processing stage and is usually heterogeneous within a product, while in long-fibre composites, the fibre orientation is chosen by design. This session focuses on a fundamental and quantitative understanding and prediction of the mechanical behaviour of various polymer systems and how their mechanical properties depend on the structure and on the processing conditions creating this structure. Contributions and new developments in the characterization and prediction of the elastic-(visco)-plastic response and early stages of damage and failure at different length scales of various polymer systems are of interest, including continuum and atomistic modelling approaches. Combined experimental and numerical approaches for proper parameter identification and predictions are also welcome.
