Classical calibration procedures for phenomenological thermo-elasto-viscoplastic constitutive models usually involve a large number of tests to identify all the material parameters, leading long experimental campaigns. In present work, novel methodology that takes full advantage full-field measurements heterogeneous test is proposed. It relies on an innovative combination Virtual Fields Method ...

the effects of unleaded gasoline and unleaded gasoline–ethanol blends on engine performance and pollutant emissions were investigated experimentally in a single cylinder, four-stroke spark-ignition engine with variable engine speeds (2600–3500 rpm). four different blends on a volume basis were applied. these are e0 (0% ethanol + 100% unleaded gasoline), e3 (3% ethanol + 97% unleaded gasoline), ...

This paper present the experimental inquiry on heat transfer and friction features enrichment adopting new-fangled of three side’s synthetically rugged rectangular duct solar air heaters (SAHs). The roughened SAH ducts has been an arrangement multi-v transverse wire (top wall two side walls transverse) covered with glass sides. It various appliances such as crop drying, seasoning timber, space ...

Deneysel çalışmada, St-37 malzemesinin lazer kesme işleminde yüzey pürüzlülüğünü (Ra) ve kerf genişliğini (KG) etkileyen parametreleri deneysel istatiksel olarak incelenmiştir. Lazer deneylerinin maliyetini azaltmak için parametrelerinin tasarımı Taguchi L32 (21x42) dikey dizilimine göre oluşturulmuştur. parametresi iki farklı frekans (2500 3500 Hz), dört gaz basıncı (0,8, 0,9, 1 1,1 bar) hızı ...

Abstract The flow behavior of a novel Cr-Si alloyed hot stamping steel (Cr-Si steel) at elevated temperature was investigated via isothermal compression tests on Gleeble-3500 thermomechanical simulator with range 600 ~ 900 ℃ and strain rate 0.1~10 s-1. Subsequently, the Arrhenius-type constitutive model, comprising compensation, established in accordance friction adiabatic heating corrected str...
