J. Cent. South Univ. (2021) 28: 297-310 DOI: https://doi.org/10.1007/s11771-021-4603-3 Geotechnical stability analysis considering strain softening using micro-polar continuum finite element method.... Due to the coupling effects of lc and strain softening, softening behavior of geomaterial tends to be postponed. Additionally, the bearing capacity of a geotechnical system may be significantly......
J. Cent. South Univ. Technol. (2011) 18: 1619-1625 DOI: 10.1007/s11771-011-0881-5 Strain field investigation of limestone specimen under uniaxial compression loads using particle image velocimetry..., global filter and local filter. The cubic interpolation was utilized if the displacements without a number were encountered. The full-field strain was then obtained using the local least square method......
Determination of strain criterion of Portevin–Le Chatelier effect for aluminum alloy sheets WAN Min(万 敏)1, HAN Jin-quan(韩金全)1, JIN Hai-xia(金海霞)1, WU Hui(伍 惠)2, DONG Jin-liang(董锦亮)2, LI Bing(李 兵)2...; accepted 15 September 2006 Abstract: According to the deformation state in skin stretch forming, an experiment was investigated to determine the critical strain, which make the slip line occur......

J. Cent. South Univ. (2020) 27: 1666-1677 DOI: https://doi.org/10.1007/s11771-020-4398-7 Influence of radial forging process on strain inhomogeneity of hollow gear shaft using finite element method... orthogonal design method. To examine the strain inhomogeneity of the forging workpiece, the strain inhomogeneity factor was introduced. The results reveal that the maximum effective strain......
RECRYSTALLIZATION BEHAVIOR AND PRIOR AUSTENITE GRAIN BOUNDARY CORROSION IN THE PLANE STRAIN COMPRESSION CONDITION FOR A LOW CARBON X70 PIPELINE STEEL Y.Y.Shan1,Y.S.Li2,Y.H.Li3,J.Wang4 (1.Institute... pipeline steel was studied in the plane strain compression condition. It was found that the dynamic recovery but no dynamic recrystallization occurred in the current experimental condition. A method......
