We have recently introduced the Boundary Element Tearing and Interconnecting (BETI) methods as boundary element counterparts of the wellestablished Finite Element Tearing and Interconnecting (FETI) methods. Since Finite Element Methods (FEM) and Boundary Element Methods (BEM) have certain complementary properties, it is sometimes very useful to couple these discretization techniques and to bene...

UNLABELLED PROBLEM/AIMS: Thin sections of impression materials are susceptible to tearing in gingival crevices and interproximal spaces. This study measures the tear strength of six fast and regular set impression materials after different setting times and at different tearing rates. MATERIALS/METHODS Tear strength specimens were prepared of four addition silicone materials: Aquasil (Dentspl...

Lower hybrid current drive (LHCD) with modest powers ( approximately 10% of the total power input) has been used for the first time to completely stabilize performance limiting neoclassical tearing modes in many COMPASS-D tokamak discharges. The stabilizing effect in these experiments is consistent with a reduction in the free energy available in the current profile to drive tearing modes (i.e....

Space solar missions such as Yohkoh and RHESSI observe the hard Xand gamma-ray emission from energetic electrons in impulsive solar flares. Their energization mechanism, however, is unknown. In this paper, we suggest that the internal shocks are created in the reconnection jet and that they are possible sites of particle acceleration. We examine how magnetic reconnection creates the multiple sh...

Abstract Ductile fracture is characterized by a large amount of deformation. Two mechanisms may lead to ductile failure: local tearing appear in front stress concentration region like crack or geometry changes weak part the structure can induce global collapse structure. For cracks such as those considered Leak Before Break studies, analyses and net-section criteria have been used. The present ...
