Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

The use of externally bonded Steel-Reinforced Polymer (SRP) and Steel Reinforced Grout (SRG) composites is a promising new technology for increasing the flexural and shear capacities of reinforced concrete (RC) members. The reinforcement system in these composites is a sheet made up of unidirectional cords consisting of tightly wound ultra high strength steel wires. The reinforcement can be mol...

The surfaces of strained mild steel sheet specimens were examined with scanning laser confocal microscopy. Rigorous assessments were employed to establish the form of the roughness data. The small deviations from the ideal conditions observed in these assessments indicated that the stochastic process responsible for surface roughening does not conform to stationary, Gaussian, Markov statistics....

Failure in ductile sheet metal structures is usually caused by one, or a combination of, ductile tensile fractures, ductile shear fractures or localised instability. In this paper the failure characteristics of the high strength steel Docol 600DP are explored. The study includes both experimental and numerical sections. In the experimental sections, the fracture surface of the sheet subjected t...

As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...

This paper introduces a new assessment technique to monitor the quality of coated steel sheet surfaces, mainly used in the construction industry, e.g. as cladding for commercial buildings, external surface composite panels or even domestic applications, so clearly the visual appearance is critical. Normally, these types of steel sheets are coil coated onto steel strips. After curing the coating...

The dimpling process is a novel cold-roll forming process that involves dimpling of a rolled flat strip prior to the roll forming operation. This is a process undertaken to enhance the material properties and subsequent products' structural performance while maintaining a minimum strip thickness. In order to understand the complex and interrelated nonlinear changes in contact, geometry and mate...

The cold roll bonding of Al on AISI 304L stainless steel was carried out to fabricate the Al/304L/Al clad sheet composites. The maximum bond strength of 20 N/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. The microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...
