A method for measurement of electric circuit conduction path by Scan Electron Microscopy (SEM) has been developed. It shows that current conducts through the whole surface layer of solder joints when subjected to high frequency pulse loadings, but only half of the surface layer when subjected to AC loading. The Electrical Pulse Induced Resistance Change (EPIR) profile of a symmetric solder bump...

The present investigation deals with the propagation of waves in the layer of an anisotropic fibre reinforced thermoelastic solid. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitude of displacements and temperature distribution were also obtained. Finally, the numerical solution was carried out for Cobalt material...

We investigate the performance of the routines in LAPACK and the Successive Band Reduction (SBR) toolbox for the reduction of a dense matrix to tridiagonal form, a crucial preprocessing stage in the solution of the symmetric eigenvalue problem, on generalpurpose multi-core processors. In response to the advances of hardware accelerators, we also modify the code in the SBR toolbox to accelerate ...

BACKGROUND To determine the influence of lifting speed and type on peak and cumulative back compressive force (BCF) and shoulder moment (SM) loads during symmetric lifting. Another aim of the study was to compare static and dynamic lifting models. METHODS Ten male participants performed a floor-to-shoulder, floor-to-waist, and waist-to-shoulder lift at three different speeds [slow (0.34 m/s),...

A thermo-mechanical analytical model and a corresponding macroscopic bonded joint finite element is presented for the analysis of orthotropic double lap joints subjected to combined thermal-mechanical loads. The analytical solution offers an improvement in accuracy over its predecessor, at the cost of increased solution complexity. However, to facilitate the use of this solution, it has been in...

A micromechanics based analysis to predict damage initiation in compressively loaded symmetric notched multiply laminates at efevated temperature under remote biaxial loading is described. The finite element method in conjunction with the commercial code ABAQUS® is used to solve the governing system of equations. The results obtained for the predictions are compared against a set of experimenta...

An excess heat of 100 W/cc level, 1.7 times the input power in average, and 160 MJ in total was observed for about two months by the L-H mode pulse electrolysis of a D2O/Pd cell with plane-symmetric configuration of D-loading into the Pd cathode. Very weak neutron emission was detected to show an inversely proportional correlation to the excess heat variation. To explain the observed anomalous ...

An axi{symmetric problem for a penny{shaped crack bridged by bres is considered. The study is reduced to the analysis of a hy-persingular integral equation with respect to the relative crack{face separation over a circular domain occupied by crack. The special case of a large crack subjected to Mode{I loading is examined. A matched asymptotic expansions technique is used in order to estimate th...
