The present research focuses on sheet stamping processes and proposes a methodology that uses the Nakazima test to characterize the formability of the material and to develop and validate the model. In particular, the method is applied to cold (20°C) and warm (300°C) stamping of a complex automotive component made of CP ium.

Nov 03, 2020 · The quality and the formability of the sheet metal is estimated by the inverse which simplifies the overall design and manufacturing process for the standard stamping procedure of ium alloy . Hence, the mechanical properties of ium are suitable for the calculation of formability and intensive research is carried out  to analyse the
Development of an S-specimen geometry for shear testing Dec 15, 2020 · This work presents a novel S-specimen design and an associated methodology for testing pure in-plane shear failure in composites. The technique has been experimentally tested with woven thermoplastic composites which have complex failure evolution in

Materials Research E, Volume 6, Number 6, June 2019 Wear test results on commercial pure titanium (CP-Ti) indicated that despite the increase in hardness by 2.6 times after the surface mechanical attrition treatment (SMAT), wear properties of the treated samples were diminished. Samples embrittlement and wear rate
Novel Technique for Static and Dynamic Shear Testing of Abstract Few shear test techniques exist that cover the range of strain rates from static to dynamic. In this work, a novel specimen geometry is presented that can be used for the characterisation of the shear behaviour of sheet metals over a wide range of strain rates using traditional tensile test devices.
