(19940501)A threedimensional analysis of the Charpy Vnotch specimen subject to impact loading is carried out, using a data parallel implementation in a transient threedimensional finite element programme. An elasticviscoplastic ...

(19930701)The equiaxed solidification of eutectic alloys is modelled by a probablistic method. The volume of the specimen is divided into a regular network of cubic cells and the temperature is assumed to be uniform. The temperature ...

(19970101)We propose a model of equiaxed eutectic solidification that couples macroscopic heat diffusion with a microscopic description of nucleation and growth of the eutectic grains. The heat equation is solved numerically by means ...

(19971101)A threedimensional (3D) explicit finite difference model has been developed to simulate the thermal behaviour of specimens subjected to controlled thermal cycling patterns using direct resistance heating in a Gleeble ...

(19960701)Computational techniques for obtaining the electronic ground state in the ab initio pseudopotential method using a planewave basis set have been examined for SiC(110)  Al interfaces as metal  ceramic interfaces. The ...

(19980101)Ab initio planewave pseudopotential calculations for the neutral silicon vacancy indicate a formation energy of 3.6 eV, with the surrounding lattice undergoing a tetragonal distortion with the nearby atoms forming two ...

(19980901)As our title implies, we consider materials failure at the fundamental level of atomic bond breaking and motion. Using computational molecular dynamics, scalable parallel computers and visualization, we are studying the ...

(19930401)An ab initio periodic HartreeFock study of silicochabazite is presented. Complete geometry optimization has been performed using both a minimal STO3G and an extended (splitvalence plus polarization functions) basis ...

(19990701)Among many ab initio methods, the allelectron mixedbasis approach using numerical atomic orbitals confined inside nonoverlapping spheres as well as plane waves has an advantage in the application to moleculardynamics ...

(19950701)Aluminum nitride (AlN) ceramics are prospective materials for electronic parts, particularly LSI substrates, because of their excellent mechanical, dielectrical and thermal properties. Their high thermal conductivity is ...

(20000501)The solidification path of highly undercooled refractory metals and their alloys in an ultrahigh vacuum drop tube is shown to involve transitory metastable phases. Firstprinciples calculations of the structural stability in ...

(20000901)This paper describes an investigation into the suitability of Gaussian process models for predicting the microstructure evolution arising from static recrystallization. These methods have the advantage of not requiring a ...

(19960501)Hydride precipitation and dissolution in a zirconium matrix have been simulated numerically using a finite element technique. The evolution of the accommodation energy associated with such phase transformations has been ...

(19990901)This work deals with the AC electrical properties measurements under large strain of composites strongly contrasted in the viewpoint of their electrical and mechanical properties. First, the possibility to model a strongly ...

(19970501)Four linear scaling tightbinding methods (the density matrix method, bond order potentials, the global density of states method, and the Fermi operator expansion) are described and compared to show relative computational ...

(19950701)A computational methodology for nucleation of phase transformations in a class of grade 2, nonlinearly elastic materials is presented. Nucleation is treated as an energy extremum problem. The material is assumed to be ...

(19950101)A computer simulation is conducted to study singlecrystal growth by the travelingsolvent method (TSM) using a pseudosteadystate model. The model, which is governed by momentum, heat, and mass balances in the system, ...

(19951101)The formation of stable interstitial configurations in the (1121), (1122), (1011) and (1012) twin boundaries in hexagonal closed packed metals has been studied by computer simulation. The crystals have been modelled by ...

(19950301)Modelling of two types of crystallographic texture corresponding to coldrolled material (socalled copper type texture) and to completely recrystallized material (cubic texture) has been performed for hypothetical FCC ...

(19991101)Constitutive equations are derived for the linear viscoelastic behaviour of amorphous glassy polymers subjected to physical ageing. A polymer is treated as an ensemble of cages where relaxing regions are trapped. At random ...
