impeller. So it can be used as a reliable experimental method to examine the strain distribution during die forging. Key words: die forge; plastic deformation; strain distribution ... in measuring the strain and streamlines distribution during die forging of complex components. This method can not only measure but also analyze quantitatively the deformation of die forging without......
; (24) Eq.(24) is specific linear plastic work rate per unit volume with . For plane strain, it is the same with plastic work rate per unit volume by Mises’ criterion... the result of Eq.(22). For other plane strain deformations, integrating Eq.(24) to get internal deformation power is also recommended. 6 Conclusions 1) The unified linear plastic work rate done per unit......
ON THE TENSILE MECHANICAL PROPERTY OF Si-Mn TRIP STEELS AT HIGH STRAIN RATE W.Shi1,X.C.Wei1,L.Li1,R.Y.Fu1 (1.School of Materials Science and Engineering, Shanghai University, Shanghai 200072, China) Abstract:Tensile mechanical properties of 1.6Si-1.58Mn-0.195C TRIP (transformation-inducedplasticity) steels under high strain rate and effects of DP (dual-phase) treatments werestudied......

School of Mechanical &Automotive Engineering, Qilu...="ChDivSummary">The true stress-strain relationships of Ti-5Al-2Sn-2Zr-4Mo-4Cr(TC17) alloy with a wide range of strain rates were investigated by uniaxial quasi-static and dynamic compression tests......
Article ID: 1003-6326(2005)05-1125-05 Effect of deformation temperature and strain rate on semi-solid deformation behavior of spray-formed Al-70%Si alloys ZHANG Di(张 迪)1, YANG Bin(杨 滨)1... of the deformation temperature, strain rate and the microstructure were studied. Two strain rates(1s-1and 0.1s-1) and six deformation temperatures (600℃, 720℃ , 780℃, 900℃, 1000℃ and 1100℃) were chosen......

length describes the interactions and interplaying among microstructures. First, the increment of the plastic shear strain distribution in adiabatic shear band is obtained based on gradient-dependent plasticity. Then, the plastic work distribution is derived according to the current flow shear stress and the obtained increment of plastic shear strain distribution. In the light of the well-known......
Microstructure tailoring of Al0.5CoCrFeMnNi to achieve high strength and high uniform strain using severe plastic deformation and an annealing treatmentH.T.Jeong,W.J.KimDepartment of Materials Science and Engineering, Hongik University摘 要:Ultrafine-grained alloys fabricated by severe plastic deformation(SPD) have high strength but often poor uniform......
in strain softening rock mass around a newly formed cavity are derived with a three step-wise elasto-plastic model. Hoek-Brown criterion is adopted as the yielding criterion of rock mass. Damage... decrease with the increase of the damage factor. The displacement of the cavity wall for the case with maximum plastic bulk strain is nearly twice than that with no dilation. Rock mass moves more toward......
