Lightweight materials, such as titanium alloys, magnesium and aluminium are characterised by unusual combinations of high strength, corrosion resistance, low weight. However, some the grades these alloys exhibit poor formability at room temperature, which limits their application in sheet metal-forming processes. materials used extensively automobile aerospace industries, leading to increasing ...

Abstract In sheet metal stamping, the occurrence of strain localization in a deformed is considered failure. As so, metal’s formability conventionally evaluated using Forming Limit Diagram (FLD), which separates principal space into safety and unsafety regions by Curve (FLC). This study presents an evaluation method for detecting based on Digital Image Correlation (DIC) during experiment. The c...
