Ductile Failure in High Strength Steel Sheets
Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usag...
متن کاملModelling of Failure in High Strength Steel Sheets
In this theses the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M are studied. Constitutive laws and failure models are calibrated and verified by the use of experiments and numerical simulations. For the constitutive equations, an eight parameter high exponent yield surface has been adopted, representing the anisotropic behaviour, and a mixed isotropic-kinematic ...
متن کاملFailure of high strength steel sheets: Experiments and modelling
Failure in sheet metal structures of ductile material is usually caused by one of, or a combination of, ductile fracture, shear fracture or localised instability. In this paper the failure of the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M is explored. The constitutive model used in this study includes plastic anisotropy and mixed isotropic-kinematic hardening....
متن کاملFormability Analysis of Diode-Laser-Welded Tailored Blanks of Advanced High-Strength Steel Sheets
Currently, advances due to tailored blanking can be enhanced by the development of new grades of advanced high-strength steels (HSSs), for the further weight reduction and structural improvement of automotive components. In the present work, diode laser welds of three different grades of advanced high-strength dual-phase (DP) steel sheets (with tensile strengths of 980, 800, and 450 MPa) to hig...
متن کاملBond of High Strength Concrete with High Strength Reinforcing Steel
This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
