This paper presents an investigation to establish the link between friction welding process parameters and the ultimate tensile strength (UTS) of friction-welded titanium joints by application of an artificial neural network (ANN) technique. The experimental matrix is based on a central composite design with parameters varied at five levels. The UTS of the joints was modeled by the application of...
This study is focused on the role of hydroxyapatite (HA) nanoparticles and graphene oxide (GO) nanoplates on the flexural and compression properties of epoxy-based hybrid nanocomposites. In the first step, epoxy-based hybrid nanocomposites were reinforced by different HA nanoparticles and GO nanoplates up to 7 wt% and 0.5 wt%, respectively. Filler’s weight fractions that used as design parameters...
The short-circuit gas metal arc welding has been continuously studied over the years, due to its important role in manufacturing processes. Concerning the process, many kinds of research are carried out aiming to understand the influence of the shielding gas in welds quality. In this context, this work treats the voltage and current welding signals as time series and applies a feature extraction based...
