It is important to consider variations in material parameters in the design of automotive structures in order to obtain a robust and reliable design. However, expensive tests are required to gain complete knowledge of the material behavior and its associated variation. Consequently, due to time and cost constraints, simplifiedmaterial scatter modeling techniques based on scatter data of typical...

Dissimilar material joining between magnesium (AZ31B) alloy and dual-phase steel (DP600) was achieved using the friction stir welding (FSW) process. The present work aimed at studying effect of tool rotational speed on microstructure mechanical properties dissimilar joints. joints were fabricated speeds 800 1600 rpm with weld 50, 100, 150 mm/min, respectively. plunge depth 0.2 mm tilt angle 2° ...

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...

This work proposes a simulation approach to characterize the behavior of DP600 steel subjected micro indentation tests. Axisymmetric and three-dimensional artificial RVEs were generated with statistical data from metallographic images. FEM simulations tests used Gurson model Rodriguez-Gutierrez equation. There is proposed new parameter called spherical radius quantify closeness hard particles i...

In most forming processes based on tailored blanks, the tool material remains the same as that of sheet metal blanks without tailored properties. A novel concept of lightweight construction for deep drawing tools is presented in this work to improve the forming behavior of tailored blanks. The investigations presented here deal with the forming of tailored blanks of dissimilar strengths using t...
