In this paper to predict the critical conditions for onset of elastic-plastic wrinkling of flange of a two-layered circular blank during the deep-drawing process a closed-form semi-analytical elastic-plastic solution using Tresca yield criterion alongwith deformation theory in plasticity with considernig the perfectly plastic behaviour of materials is presented. Simplifying the presented soluti...

The aim of this paper is to investigate adhesion property between nano-layered filler and the polymer matrix using a combination of experimental and micromechanical models as well as the changes in yield strength and stiffness of a layered silicate-filled epoxy nanocomposite. The results indicate that addition of intercalated layered silicate particles increased Young’s modulus and yield streng...

[1] Small volcanic edifices, shields with a diameter less than about 20 km, are common and sometimes very abundant features on the plains of Venus. Typically, they form tight or loose clusters of features known as shield fields. Small shields are interpreted to be formed due to small-scale eruptions through numerous and distinct sources, a mode of formation apparently significantly different fr...

Rubble mound near-bed structures are among the more common hydraulic structures. Examples include bottom protections to prevent scour near bridge piers, offshore structures, weirs and sluices and at the toe of bank protections or breakwaters, but also pipe covers on offshore pipelines. The cornerstone of the theory behind the design of these structures was laid by Izbash (1930) and, most notabl...

Abstract We examine how creditor rights affect the trade-off between non-debt and debt tax shields. Using four bankruptcy reforms a panel of private public firms from Italy, we show that laws empowering creditors reduce avoidance increase financing, consistent with substituting shields corroborate validity our findings using across 33 countries. Additionally, document impact protection is mitig...

rotavirus, a triple-layered non-enveloped member of the reoviridae family, obtained a transient membrane envelope when newly synthesized subviral particles bud into the endoplasmic reticulum (er). as rotavirus particles mature, they lose their transient membrane and obtain outer layer. it is mostly believed that only double layered particles bud into the er. the present study describes that the...

It is shown that the Shields–Harary index of vulnerability of the complete bipartite graph Km,n, with respect to the cost function f (x)= 1− x, 0 x 1, is m, if n m+ 2√m, and 1 n+1 (n+m) 2 4 , ifm n<m+ 2 √ m. It follows that the Shields–Harary number ofKm,n with respect to any concave continuous cost function f on [0, 1] satisfying f (1)=0 ismf (0), if n m+2√m, and between 1 n+1 (n+m) 2 4 f (0) ...

Retaining and applying knowledge enables an organization to know what to do, how to do it, and when to do it, empowering it to succeed in competitive situations. Data warehouses store data and can be a source of knowledge but do not store knowledge directly. However, knowledge in the sense of procedures, best practices, business rules, expert knowledge, facts within context, and processed data ...

HTS bulks present a high critical current density which can be used as magnetic shields. Previous works showed that BSCCO bulks can screen magnetic fields up to 0.1 T. For large scale applications like electrical machines, stronger magnetic field is usually needed. In so doing, (RE)BCO materials are more suitable since they can shield much higher magnetic fields. Another key issue concerns the ...
