Reproducing hoop stress–strain behavior for tubular material using lateral compression test

摘要: Abstract Identification of material properties in the hoop direction, such as stress–strain behavior, is essential tube hydroforming processes. Conventional tests uniaxial tension and compression have some drawbacks limitations. In current investigations a simple technique to identify behavior direction for tubular introduced, based on experimental data obtained from lateral test. proposed technique, an assumed curve used finite element simulation predict load deflection compression. An iterative algorithm compare calculated curves until good agreement with percentage deviation less than 4% obtained. The suggested was obtain Cu–40%Zn brass tube. predicted compared that Comparison between showed effective prediction test 1%.
