This paper presents a new approach to describe the mechanical behavior of semi-crystalline polymers, the plastic deformation of which is determined by their two-phase structure. To describe the plastic behavior of semi-crystalline polymers, a two-pha

Typically, the plastic yield stress of a sample is determined from a stress-strain curve by defining a yield strain and reading off the stress required to attain it. However, it is not a priori clear that yield strengths of microscale samples measure

We compute the probability distribution density of mutual forces between edge and screw dislocation assemblies. The distribution is directly related to the internal stress distribution and can be revealed experimentally from x-ray profiles. Using num
