1. 1. Mechanical behaviour of glassy polymers: experiments and modelling

   Författare :Jonas Engqvist; Hållfasthetslära; []
   Nyckelord :;

   Sammanfattning : This thesis presents experimental investigation and modelling of the mechanical response of glassy polycarbonate (PC) during deformation. The mechanical response is studied experimentally over a wide range of length-scales using X-ray scattering techniques and optical full-field deformation measurement by Digital Image Correlation (DIC).
