Transformation-induced plasticity (TRIP) steels are part of advanced high strength steels capable of phase
transformation, having good strength and ductility. The transformation rate is known to be dependent on the stress state, which
may lead to asymmetric hardening behaviour...
In the automotive engineering community, the modified maximum force criterion proposed by Hora and coworkers
is considered acceptable for theoretically estimating the forming limit curve (FLC) of sheet metals. Based on this
criterion, a graphical method is proposed to simplify...
Ultra-high strain rate deformation (> 104 s-1) is common in high speed manufacturing and impact engineering.
However, a general constitutive model suitable for describing the material deformation at ultra-high strain rates is still
unavailable. The purpose of this study is of ...
Electrodeposited zinc layers help prevent the corrosion of steel surfaces. The microstructure, surface
morphology, and texture of the electrodeposits are related to the deposition variables. Herein the surface morphology and
microstructure are investigated as functions of the ...
With the improvement in the accuracy of simulation and computation time, the need for the application of
optimization technique in designing process parameters is increasing and is being realized in some fields. However, two
obstacles are still preventing the optimization tech...
Surface deflection is a phenomenon that causes fine wrinkles on the outer surfaces of sheet metal and
deteriorates product external appearance. It is quantitatively defined as the difference between the section curve of the sheet
and the ideal curve. In this study, using neura...
Recently, as the demands to improve automotive fuel efficiency grow, several attempts are being conducted on
the development of lightweight automotive components using magnesium (Mg) alloy sheets having the highest specific
strength among metal materials. In a window regulator...
Success of the numerical simulations depends on the accuracy of the material constitutive relations. Most of the
ductile materials exhibit increased strain rate sensitivity at higher strain rates (> 103 s1) compared to low and medium strain
rates. Meanwhile, plastic deformat...
The paper presents the results of forming rifts in five-layer fiber reinforced metal polymer laminates by electromagnetic
forming. During the experimental studies the discharge energy of the electro-magnetic machine was varied in such
a way as to achieve different depths of th...
This study proposes a fast running model that interconnects input and output data for a single-pass cold bar
drawing process through the use of Artificial Neural Network (ANN) and automatically generated a large volume of elasticplastic
finite element (FE) analysis results. Th...
