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 کاملInfluence of Strain History on Ductile Failure of Steel
Notched tensile bars of a high strength structural steel were loaded to void coalescense. The resuIts show that the damage curve determined using radially loaded specimens is not valid for specimens under nonradial loading. The results of the experiments with different load histories of notched tensile bars show, that a single parameter criterion like a damage parameter is not sufficient to des...
متن کاملEffect of Constraint on Ductile Crack Growth and Ductile-Brittle Fracture Transition of a carbon Steel
Ductile-brittle fracture transition was investigated using compact tension (CT) specimens from -70 o C to 40 o C for a carbon steel. Large deformation finite element analysis has been carried out to simulate the stable crack growth in the compact tension (CT, a/W=0.6), three point-point bend (SE(B), a/W=0.1) and centre-cracked tension (M(T), a/W=0.5) specimens. Experimental crack tip opening di...

This paper reviews selected recent innovations that expand the range of applicability of a number of new and emerging structural steel systems that can provide effective seismic performance. Focus is on recent developments on: (a) Steel Plate Shear Walls having light gauge infill plates; (b) Perforated Steel Plate Shear Walls; (c) Buckling Restrained Braced frames designed to meet Structural Fu...
متن کاملThe 3-D Computational Modeling of Shear-Dominated Ductile Failure in Steel
This paper presents recent advances in the computational analysis of the failure mechanisms in high-strength steel. Computational issues are described regarding modeling of the geometry, distribution, and material behavior of the dispersed phases present in the microstructure of steel. The investigation of the failure mechanisms using computational cell model methodology in two and three dimens...
