Mechanical performance of polymer systems: The relation between structure and properties
Heh Han Meijer,Leon Le Govaert +1 more
TL;DR: In this paper, the authors introduce the concept of intrinsic deformation behavior of polymeric materials, and explain how intrinsic behavior relates to the macroscopic response of polymers, and how to construct tailored materials, either on the molecular level or in heterogeneous materials, on the micro-scale.

On the origin of strain hardening in glassy polymers
TL;DR: In this article, the influence of network density on the strain hardening behavior of amorphous polymers is studied and the network density of polystyrene is derived from the rubber-plateau modulus determined by dynamic mechanical thermal analysis.

Size effects in the processing of thin metal sheets
TL;DR: In this paper, the influence of grain sizes on the processing of thin metal sheets was investigated in two different ways: first, by reduction of the sheet thickness at a constant grain size (investigated in tension), and secondly, by changing the grain size at constant sheet thickness, and the results showed that in both the experiments, the yield strength as well as the maximum load decrease with a decreasing number of grains over the thickness.

Structure, Deformation, and Failure of Flow-Oriented Semicrystalline Polymers
Bag Bernard Schrauwen,van Lca Lambèrt Breemen,AB Anne Spoelstra,Leon Le Govaert,Gwm Gerrit Peters,Heh Han Meijer +5 more
TL;DR: In this paper, the influence of processing induced crystalline orientation on the macroscopic deformation and failure behavior of thin samples of polyethylene and polypropylene was investigated by optical microscopy, X-ray diffraction techniques, and transmission electron microscopy.

Modeling of the Postyield Response of Glassy Polymers: Influence of Thermomechanical History
TL;DR: In this paper, a validated constitutive relation that is able to describe the deformation behavior of polycarbonate over a large range of molecular weights and thermal histories, with one parameter set only, is presented.
