A phenomenological constitutive law for the nonlinear viscoelastic behaviour of epoxy resins in the glassy state
TL;DR: In this paper, a constitutive model is proposed to describe the nonlinear viscoelasticity of epoxy resins in the glassy state, which allows simulation of this cyclic behaviour and, in particular, of the flex which characterises the stress-strain curve upon unloading.
Journal ArticleDOI
Preparation and mechanical characterization of laser ablated single-walled carbon-nanotubes/polyurethane nanocomposite microbeams
TL;DR: In this paper, the preparation of nanocomposites consisting of laser synthesized single-walled carbon nanotubes (C-SWNTs) reinforcing a polyurethane was described.
Journal ArticleDOI
Modeling the Temperature Dependence of Dynamic Mechanical Properties and Visco-Elastic Behavior of Thermoplastic Polyurethane Using Artificial Neural Network
TL;DR: The multi-layer feed-forward back-propagation artificial neural network has been confirmed to be a very effective artificial intelligence tool for the modeling of dynamic mechanical properties and for the prediction of visco-elastic behavior of tested thermoplastic polyurethane in the whole temperature range of its service life.
Journal ArticleDOI
Relaxation dynamics of a polymer network modeled by a multihierarchical structure
TL;DR: In the framework of generalized Gaussian structures, by making use of the eigenvalue spectrum of the connectivity matrix, the averaged monomer displacement under local external forces as well as the mechanical relaxation quantities (storage and loss moduli) are determined.
Journal ArticleDOI
A Tensile Strain Hardening Test Indicator of Environmental Stress Cracking Resistance
TL;DR: In this article, a tensile strain hardening test was proposed to offer a faster way to characterize environmental stress cracking resistance (ESCR) of polyethylene in structural and polymer pipe applications, and a practical approach is adopted whereby the test is extended to room temperature and shown to relate reliably to the ESCR of HDPE.

The Determination of the Elastic Field of an Ellipsoidal Inclusion, and Related Problems
TL;DR: In this paper, it is shown that to answer several questions of physical or engineering interest, it is necessary to know only the relatively simple elastic field inside the ellipsoid.
Journal ArticleDOI
The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.
Journal ArticleDOI
Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
