A method for calculating damage evolution in adiabatic shear band of titanium alloy WANG Xue-bin(王学滨) College of Mechanics and Engineering, Liaoning Technical University, Fuxin 123000, China...; Abstract: A method for calculating the evolution of the local damage variable at the adiabatic shear band (ASB) center was proposed. In the present method, the JOHNSON-COOK......

microstructural effect beyond the occurrence of shear strain localization, the distributions of local plastic shear strain and deformation in adiabatic shear band(ASB) were analyzed. The peak local... critical plastic shear strain is reached, the least apparent shear localization occurs. Key words: adiabatic shear band; ductile metal; shear localization; JOHNSON-COOK model; constitutive parameters ......

strain rate, dislocation glide and twinning are present at the same time. At the strain rate of 2 964 s-1, adiabatic shear band can be found easily, even at the strain rate of 1 537 s-1 adiabatic shear localization zone can be found. In adiabatic shear localization zone, there are fine recrystallization grains. But in adiabatic shear band, the grains cannot be identified by optical......
. The results show that it is not a flat surface but a shear band that yields in the sample. The curve of particle velocity vs distance from the designed shear surface of test model that is taken as a datum plane...Mesomechanical simulation of direct shear test on outwash deposits with granular discrete element methodSHI Chong(石崇)1,2, WANG Sheng-nian(王盛年)1,2, LIU Lin(刘琳)1,2, MENG Qing-xiang(孟庆祥)1,2, ZHANG......
