Five methods are introduced for design of castellated I beams encased in concrete. One of the methods, plastic analysis, is thoroughly explained and the relevant equations are developed. Eight castellated I beams encased in concrete are made and tested. The theoretical design methods are all compared with the test results and the safety factor for each method is calculated. The results show tha...

 This paper is concerned with numerical simulation of plastic modes of tubular structures. The simulation incorporates with finite element limit analysis based on the upper bound method and the minimization technique. The analysis considers sequential deformation of structures with work-hardening effects. The simulation results demonstrate plastic buckling is one of the collapse modes and occu...

plastic recycling is the process of recovering scrap or waste plastics and reprocessing thematerial into useful products that sometimes differ completely in form from their original state. an importantissue in plastic recovery and recycling is that plastic waste usually contains a variety of plastics that differ intheir physical and chemical properties. separation of recovered plastics into dis...

in many cases, a torsional shaft may be a thick-walled radially inhomogeneous cylindrical object. the hollow shafts made of functionally graded materials (fgms) are such kind of compositions which were studied in this paper. cylindrical fg shafts are composed of ceramic and metallic parts with power function distribution across the radial direction. the ceramic phase is isotropic elastic and th...

This document is the second deliverable produced within WP2 in the PLASTIC project. This deliverable describes the PLASTIC UML2 profile that concerns the starting point of the whole PLASTIC development process (described in PLASTIC Deliverable D2.1 – http://wwwc.inria.fr/plastic/deliverables/plastic-d2_1-finalpdf.pdf/download). It is a concrete implementation of the PLASTIC conceptual model (de...
