Application of the expanded distinct element method for the study of crack growth in rock-like materials under uniaxial compression

Lei YANG, Yujing JIANG, Bo LI, Shucai LI, Yang GAO

Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 2,   Pages 121-131 doi: 10.1007/s11709-012-0151-0

Abstract: The tensile-shear failure criterion and the Griffith failure criterion were implanted into the EDEM toSimulation results indicated that the EDEM model with the tensile-shear failure criterion has strongThe EDEM model with the Griffith failure criterion can only simulate the splitting failure of samplesdue to tensile stresses and is incapable of providing a comprehensive interpretation for the overall(in the form of tensile wing cracks and shear secondary cracks) and the coalescence of two cracks due

Zhang Baoping,Ding Chuntong,Liu Baohua,Chen Xuelian

Strategic Study of CAE 2003, Volume 5, Issue 3,   Pages 44-50

Abstract:

The shock tensile stress-strain curves of 93% wt. tungsten alloy at different strain rates εand different temperatures T were measured experimentally by use of a Hopkinson tensile bars equipmentBased on these experimental data, two constitutive models were proposed to represent the shock tensileand the plastic work W1 at the maximum load-onset of instability was derived, so that the criterionof shock tensile fracture of the material is given in this paper.
