Asymmetric rolling (ASR) is a method to manufacture sheet metals with the aim of improving material performance. The objective present work investigate effect asymmetric on an aluminum alloy used in automotive industry. To this end, three parameters process were studied, namely asymmetry factor (1, symmetric (SR) and 1.36, (AR)), thickness reduction per pass (10%, 15%, 30%), routes (asymmetric ...

Purpose – To introduce recent research and development of biopolymer deposition for freeform fabrication of three-dimensional tissue scaffolds that is capable of depositing bioactive ingredients. Design/methodology/approach – A multi-nozzle biopolymer deposition system is developed, which is capable of extruding biopolymer solutions and living cells for freeform construction of 3D tissue scaffo...

Over the last decade considerable effort has been put in the development of techniques to assess the performance and the dependability of computer and communication systems in an integrated way. This so-called per-formability modelling becomes especially useful when the system under study can operate partially, which is for instance the case for fault-tolerant computer systems and distributed s...

Hot stamping is a method capable of manufacturing high-strength automotive body parts by inducing martensitic phase transformation through forming and die quenching after heating metal sheet into high temperature austenite phase. However, it not easy to solve various formability problems occurring in the hot process due complexity material behavior during forming. In this study, fracture-relate...

The micromechanics of the formability a lean duplex TRIP steel was investigated using Synchrotron X-Ray Diffraction (S-XRD) measurements and Crystal Plasticity Finite Element Modeling (CPFEM). Specifically, effect ferrite phase on reduction stress concentrations in martensite influence austenite texture distribution deep-drawn were studied comparison to case. A series deep-drawing processes car...

Abstract In this work it is assessed the potential of combining conventional and incremental sheet forming processes in a same metal. This so-called hybrid approach performed through manufacture pre-forming by forming, followed forming. The main objective analyzing strain evolution. induced stage will determine paths, directly influencing strains produced process. To conduct study, processes, w...

Dual-pressure tube hydroforming (THF) is a tube-forming process that involves applying fluid pressure to tube’s inner and outer surfaces achieve deformation. This study investigates the effect of dual-pressure loading paths on material formability tribological conditions. Specifically, pear-shaped triangular cross-sectional parts were formed using modes where inside tubular blank was alternated...
