This paper is a sequel to the authors’ articles which provided test data on progressive collapse of full-scale steel stiffened-plate structures without and with passive fire protection (PFP) under lateral patch loading in fires [1,2]. presents new computational models for analyses heat transfer fire-induced behaviour stiffened plate or PFP. For this purpose, transient thermal elastic-plastic la...

Abstract In forming processes, friction is a local phenomenon influenced by the contact conditions at tool-sheet metal interface. A multi-scale model applicable for coated sheets developed boundary lubrication regime which accounts physical behavior of coating and measured surface topographies sheet tools. The patches therefore real area determined interface different loading conditions. single...

one of the methods for the improvement of soil against the tensile stresses is using the artificial supplements in soil such as metal belts or nets, polymer materials and natural fibers. technically this method is called the reinforced of soil.  when a pavement is located on soft soil, great deformations can occur as a result of the crossing of traffic load in superstructure layers of the body....

Sprayed FRP is a novel method developed at the University of British Columbia which has been very successful in repairing damaged structures is Sprayed FRP. The key to a successful and optimal usage of FRP in strengthening and rehabilitation is in our ability to understand and effectively engineer SubstrateFRP bond. In this paper, performance of FRP as a repair material is studied by structural...

Composite polymer/ceramic filaments for material extrusion-based fused filament fabrication additive manufacturing, using barium strontium titanium oxide (BST) ceramics and acrylonitrile butadiene styrene (ABS) thermoplastics were produced; their dielectric physical properties have been characterised the first time. The properties, relative permittivity (εr), quality factor (Q×f) loss (tanδ) me...

background: cutaneous manifestations are commonly observed in the neonatal period. it is important to differentiate physiologic skin lesions from pathologic ones to avoid parents’ concerns. regarding this, the current study aimed to investigate the frequency and localization of salmon patch (sp) and mongolian spot (ms) in iranian newborns to assess the potential relationship between the neonata...
