Eurocode allows for finite element modelling of plated steel structures, however the information in the code on how to perform the analysis or what assumptions to make is quite sparse. The present paper investigates the deterministic modelling of flexural column buckling using plane shell elements in advanced non-linear finite element analysis (GMNIA) with the goal of being able to reestablish the...
The automotive installation soleplate part researched in this paper is made by the high strength steel. It has a very complex shape and is difficult to be deformed. The forming processes of the installation soleplate part include blanking, deep drawing, local forming and bending, etc. To obtain the reasonable strip layout design and the multi-position progressive die with the characteristics of high...
Bolted connection under static shear has been widely used in steel structural application, whose design methods are different in different codes. Especially with the development of high strength steel, the validity of current design methods should be well checked. According to GB50017-2003, Eurocode 3, ANSI/AISC360-05, BS5950 and AS4100, bolted connection under static shear is contrasted for the design...
High strength steels, which contain alloy elements like Si and Mn, are desired for automotive applications in order to develop lightweight cars with sufficient strength. In this case, oxidation layer monitoring and control on the steel surface is necessary to guarantee high surface wettability of those steels in galvanizing. Oxidation layer measurement using visible and near infrared reflectance spectrum...
Application of hot stamping technology of advanced high strength steel is one of the effective approaches for automotive light-weighting. It is important to investigate the effects of hot stamping process parameters on forming quality for the application of hot stamping technology. A kind of hot stamping tool system for process tests of U-shape sample is introduced. It includes cooling system and...
The material parameters of Chaboche nonlinear isotropic/kinematic hardening rule were identified based on the stress-stain curve of DP600 and Hill'48 yielding criterion. A FEM model was established in ABAQUS to investigate effect of different hardening rules on springback prediction for an open-channel shaped part. According to the FEM results, the prediction based on Chaboche nonlinear isotropic/kinematic...
In this paper, we consider interactions between life cycle emissions and materials flows associated with lightweighting automobiles. The study begins by developing scenarios for lightweighting a specific compact sized vehicle based on a Ford Focus. Both aluminum and high strength steel are used, and specific levels of lightweighting are considered between 6% and 23% based on literature references...
