A theoretical and experimental analysis of cold-formed steel shapes subjected to bending - Channel and simple lipped channel
(2000-12-01)
Cold-formed steel shapes have been widely employed in steel construction, where they frequently offer a lower cost solution than do traditional laminated shapes. A classic application of cold-formed steel shapes is purlins ...
Estudo da corrosão por fresta no aço inoxidável AISI 409 tratado por SHTPN
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2015-06-30)
It is estimated that corrosion is liable to affect 25% of world production of steel per year, and the economic losses due to this phenomenon may represent 2- 5% of the Gross Domestic Product (GDP). In Brazil, losses may ...
Comparison of Mechanical and Microstructural Characteristics in Maraging 300 Steel Welded by three Different Processes: LASER, PLASMA and TIG
(2015-01-01)
The maraging steel are considered ultra high strength due to its yield strength greater than 1400 MPa and are part of a set of advanced materials of interest for technological development, mainly for aeronautics and aerospace ...
Springback comparison between DP600 and DP800 steel grades
(2020-01-01)
A comparative study of the springback effect, otherwise known as elastic return, on Dual Phase DP600 and DP800 steel sheets is reported herein, which have been widely used in the automotive industry due to having good ...
Microstructural Characterization of Maraging 300 Steel Fabricated by Select Laser Melting
(2021-01-01)
3D printing of components using a layer-based deposition of materials is referred to as additive manufacturing (AM). The ability to build complex geometry components, reduce waste and avoid assembly are the main advantages ...
