Critical Specimen Sizes for Tensile-Shear Testing of Steel Sheets

Tensile-shear testing results are influenced not only by the quality of spot welds, but also by the dimensions of testing specimens. Experimental and numerical studies have been conducted on determining critical sizes for tensileshear testing of resistance spot welded specimens. Statistical methods have been employed, from planning stages to the analysis of results, for the purposes of getting ...

An Experimental and Numerical Study of Forming Limit Diagram of Low Carbon Steel Sheets

The forming limit diagram (FLD) is probably the most common representation of sheet metal formability and can be defined as the locus of the principal planar strains where failure is most likely to occur. Low carbon steel sheets have many applications in industries, especially in automotive parts, therefore it is necessary to study the formability of these steel sheets. In this paper, FLDs, wer...

Characterization of Microstructure and Mechanical Properties of Resistance Spot Welded DP600 Steel

Resistance spot welding (RSW) as a predominant welding technique used for joining steels in automotive applications needs to be studied carefully in order to improve the mechanical properties of the spot welds. The objectives of the present work are to characterize the resistance spot weldment of DP600 sheet steels. The mechanical properties of the welded joints were evaluated using tensile-she...

Glassy steel optimized for glass-forming ability and toughness

An alloy development strategy coupled with toughness assessments and ultrasonic measurements is implemented to design a series of iron-based glass-forming alloys that demonstrate improved glass-forming ability and toughness. The combination of good glass-forming ability and high toughness demonstrated by the present alloys is uncommon in Fe-based systems, and is attributed to the ability of the...
