Thermal conductivity of anisotropic, inhomogeneous high-density foam calculated from three-dimensional reconstruction of microtome images

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1051782

An effective method is developed to predict the thermal conductivity of thick foam insulation on offshore oil and gas pipelines. High-resolution three-dimensional (3D) images (212 megavoxels) spanning macroscopic sample volumes (38 × 19 × 4 mm3) are obtained and used to create a 3D geometry of the f...

DETERMINING THE MORPHOLOGY OF CHEMICALLY FOAMED PIPE COATING USING IMAGE SEGMENTATION

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S21525

A method for rapidly characterizing the shape, size and distribution of bubbles in foam has been developed. The method is based on the extraction of bubble shapes from high resolution images of microscopy slices of the foam, using image segmentation. The foam studied is the 30 mm thick high impact p...

USE OF DIGITAL IMAGE CORRELATION AND INVERSE MODELING TO DETERMINE RESIDUAL STRESS IN AXISYMMETRIC POLYMER COMPONENTS

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S21528

This paper presents a new method to determine residual stress profiles in cables and other axisymmetric objects using digital image correlation and inverse modeling. 3D digital image correlation with two cameras and stereo-vision was used to determine full-field displacements resulting from cutting ...

Influence of the plastic potential on the mechanical response of thermoplastic components

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+899114

A new developed hyperelastic-viscoplastic constitutive model for thermoplastic materials was recently proposed [1]. The model involves the mechanical response due to intermolecular resistance, and an entropic hyperelastic response due to re-orientation of molecular chains. A Neo-Hookean material mod...

METHOD FOR THE MANUFACTURE OF POLYBRANCHED ORGANIC/INORGANIC HYBRID POLYMERS

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S12422

Polybranched organic/ inorganic hybrid polymer and method for its manufacture. The hybrid polymer has the form of an inorganic core carrying organic branches. The core is first prepared by controlled hydrolysis and condensation of a silane with a structure: X-B- Si(-Y)3 in which X= NRl R2, while R1,...

Warpage-crystallinity relations in rotational molding of polypropylene

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S13708

The authors present a study of the crystalline properties of selected series of polypropylene (PP) materials in relation to their warpage at conditions relevant for rotational molding. The PP materials have different crystallization temperatures and kinetics. The authors study the crystalline featur...

The problem of die drool in the extrusion of recycled polyethylene

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S13712

Present understanding of the formation of die drool is reported in light of the current developments in materials for blown film polyethylene (PE). Two series of samples were collected from a blown film line and the material from the die drool and the die channel, or blown film, were analysed separa...

Crystallinity in ethylene-1-hexene copolymers determined by 1H- and 13C NMR in a comparative study

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1271965

The 13C DD-MAS spectra of six ethene/1-hexene (E/H) copolymers were fitted simultaneously to a sum of four pseudo Voigt functions in which two were assigned to the alltrans crystalline region. These two peaks possessed the same chemical shift but differed in both line width and line shape. Regarding...
