A parametric macro model for a single and dual conductor power cable for transient thermo-electrical coupled simulation in PSPICE will be derived. The articledepicts the modelling of a simplified, singleand dual conductor cable and its use during simulation. Its verification against experiment and finite element simulation shows a good agreement. The derived singleand dual conductor PSPICE cabl...

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the lead center for NASA's scientific and technical information. The NASA STI Program Office provides ...

A novel micromechanics based damage model is proposed to address failure mechanism of defected solids with randomly distributed penny-shaped cohesive micro-cracks (Barenblatt–Dugdale type). Energy release contribution to the material damage process is estimated in a representative volume element (RVE) under macro hydrostatic stress state. Macro-constitutive relations of RVE are derived via self...

A micro-mechanics damage model is proposed based on homogenization of penny-shaped cohesive micro-cracks (Barenblatt–Dugdale type) in a three dimensional representative volume element. By assuming that macro-hydrostatic stress state has dominant effect on permanent crack opening, a class of pressure sensitive yielding potentials and corresponding damage evolution laws have been derived. The mer...

Successful analysis in SAS often requires lengthy repetitive steps; the same code is executed on numerous data points. Iteration of SAS code is often easily achieved with the use of Macro Arrays. The programmer can employ numerous methods for creating these arrays, as well as choosing among different structural designs. PROC SQL and the SAS DATA step can each provide clear advantages to the cre...

Adaptive learning support is a key element of high quality preschool education and includes the planning situations teacher–child interactions. The provision effective adaptive in kindergarten challenging. This longitudinal experimental study examined impact two professional development programs on 132 teachers. One program focused interactions (micro-adaptive support), other planning, preparat...

The aim of the research is to determine macro (Ca, Mg, P and K), micro (Fe, Mn, Cu, Zn Be) element heavy metal (Al, Cr, Ni, Se Cd) contents some Astragalus taxa collected from nature. Nine (Astragalus gummifer, A. compactus, lineatus var. longidens, aureus, onobrychis, declinatus, lineatus, oocephalus subsp. stachyophorus, inereus) natural areas Bingöl province were used as plant material resea...

Abstract The Nakajima test is a well-known material from the steel and metal industry to determine forming limit of sheet metal. It demonstrated how FE2TI, our highly parallel scalable implementation computational homogenization method FE $$^2$$ 2 , can be used for simulati...
