  1. Numerical modeling of mixed mode multiple crack propagation and its application to the simulation of nonlinear rock deformation and borehole breakout

    Du, Wei, 1962-The University of Arizona.1997

    Rock is a very heterogeneous material, containing structural weakness at all scales. These weaknesses include grain boundaries, pores, and cracks on the small scale, and joints, faults, and bedding planes on the large scale. Nonlinear rock deformation in the low-temperature, low-confinement regime …

  2. Three -Dimensional Discrete Element Simulation for Granular Materials

    Zhao, DaweiUniversity of Illinois at Urbana-Champaign2015

    BLOKS3D is parallelized with OpenMP on NCSA supercomputers to seek higher computational speed, and a speed up ratio of 3∼5 has been achieved. The largest size simulations involve more than 97,000 particles.

  3. Evaluation and Assessment of Inflow Rates in Tunnels Excavated in Jointed Rock Mass

    Moon, Joon-ShikUniversity of Illinois at Urbana-Champaign2015

    The effects of key parameters affecting groundwater inflows were investigated using 2-D Distinct Element Method Program which can take into account the coupled hydro-mechanical behavior within the rock fractures. The main concluding points of the study can be summarized as follows: (1) The …

  5. Further Development of the Total Fatigue Life Model for Weldments and Its Application to Fatigue Design

    Yung, Jong-YeongUniversity of Illinois at Urbana-Champaign2014

    Cruciform joints were fatigue tested under SAE Bracket variable loading history. Tube-to-plate welds were fatigue tested under bending and torsion loading conditions. Fatigue test results were compared with predictions made using the total fatigue life model which predicts the total fatigue life of …

  20. Failure and deformation of rocks in compression for underground design

    Jeon, Seokwon, 1964-The University of Arizona.1996

    Rock contains discontinuities at all scales. These discontinuities make rock behave in a complex way. This dissertation discusses a new approach to underground design based on the theory of rock fracture mechanics. Due to the important role of coal for energy in the US, coal which is classified as …
