This paper describes algorithms for threedimensional dynamic stress and fracture analysis using the material point method (MPM). By allowing dual velocity fields at background grid nodes, the method provides exact numerical implementation of explicit cracks in a predominantly meshless method. Crack contact schemes were included for automatically preventing crack surfaces from interpenetration. ...

In the crystal structure of the polymeric title compound, [Sr(C(10)H(6)O(6)S(2))(H(2)O)(2)](n), the naphthalene-2,7-disulfonate dianion uses one -SO(3) unit to bind to two Sr(II) cations and the other -SO(3) unit to bind to three Sr(II) cations; of the two coordinated water mol-ecules, one is monodentate to one Sr(II) cation, whereas the other bridges two Sr(II) cations. The μ(5)-bridging mode ...

Few novel cobalt(II) and copper(II) complexes [M(fmp)3]Cl2, [M(fmp)(bpy)2]Cl2,[M(fmp)(phen)2]Cl2 and [M(fmp)(phen)(bpy)]Cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,IR, electronic, EPR, mass spectra and cyclic voltammetri...

The present paper is devoted to the determination of displacement, stresses and temperature from three dimensional anisotropic half spaces due to presence of heat source. The normal mode analysis technique has been used to the basic equations of motion and generalized heat conduction equation proposed by Green-Naghdi model-II [1]. The resulting equation are written in the form of a vector –matr...

The adhesive fracture resistance of structural joints in mode II,

Abstract Experimental observations have shown that the transition characteristics of the boundary-layer flow over rotating cones depends on the cone half-angle. In particular, pairs of counter-rotating Görtler-type vortices are observed over cones with slender half-angles and co-rotating vortices are observed over broad cones. Garrett et al (2009 J. Fluid Mech. 622 209–32) have hypothesized the...

Organometallic Ru(II), Os(II) and Rh(III) complexes of lapachol induce apoptosis in human tumour cell lines in the low μM range by a mode of action involving oxidative stress, especially in the case of the ruthenium compound.

in this paper we consider the non-preemptive variant of a multi-mode resource constrained project scheduling problem (mrcpsp) with mode identity, in which a set of project activities is partitioned into disjoint subsets while all activities forming one subset have to be processed in the same mode. we present a depth-first branch and bound algorithm for the resource constrained project schedulin...
