Characterization of Semi-crystalline Polymers Using MRI

H single point magnetic resonance imaging (SPI)[1],[2],[3] has been introduced in the literature as a method for determining relaxation characteristics of semi-crystalline polymers and for extracting MRI images from such samples. The work presented in the literature to date demonstrates the applicability of this technique. In this work, SPI has been applied to the direct observation of stress-i...

Finite Element Modeling of Strain Rate and Grain Size Dependency in Nanocrystalline Materials

Nanocrystalline materials show a higher strain-rate sensitivity in contrast to the conventional coarse-grained materials and a different grain size dependency. To explain these phenomenon, a finite element model is constructed that considers both grain interior and grain boundary deformation of nanocrystalline materials. The model consist of several crystalline cores with different orientations...

Multiscale Modeling of the Deformation of Semi-crystalline Polymers

Strain rate dependency of fractures of immature bone.

Radiological features alone do not allow the discrimination between accidental paediatric long bone fractures or those sustained by child abuse. Therefore, there is a clinical need to elucidate the mechanisms behind each fracture to provide a forensic biomechanical tool for the vulnerable child. Four-point bending and torsional loading tests were conducted at more than one strain rate for the f...
