Thermal conductivity of anisotropic, inhomogeneous high-density foam calculated from three-dimensional reconstruction of microtome images
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...
USE OF DIGITAL IMAGE CORRELATION AND INVERSE MODELING TO DETERMINE RESIDUAL STRESS IN AXISYMMETRIC POLYMER COMPONENTS
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...
Numerical simulations of UD-FRC plates: A pin-hole loaded case and ballistic limit predictions
Influence of the plastic potential on the mechanical response of thermoplastic components
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...
Three-dimensional digital image correlation in constitutive property measurement and model verification
Crystallinity in ethylene-1-hexene copolymers determined by 1H- and 13C NMR in a comparative study
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...
