  • UPDATE: Interim Repairs near completion at Arkabutla Dam; Study underway for long-term solutions

    Vicksburg, Miss – The U.S. Army Corps of Engineers Vicksburg District (USACE-MVK) continues to advance interim risk reduction measures (IRRM) at Arkabutla Dam in Northwest Mississippi that are scheduled to be completed by late September 2024. These measures include adding piezometers to increase real-time monitoring of groundwater pressure and installing relief wells to relieve water pressure and to allow excess water to be diverted safely.
  • USACE funds high water plaque to honor flood-devastated Kentucky community

  • Two Rangers leading the way by example at West Point

    One of the most demanding and challenging career fields in the U.S. Army Corps of Engineers is that of park ranger. Park Rangers work around the clock to keep our USACE parks open and safe for visitors and campers. Two West Point rangers who exemplify going above and beyond are Ben Williams, the chief ranger for Natural Resource Management, and Susan Cromer, the Recreation chief ranger.
  • Comparison of Numerical Simulations of Heat-Induced Stress in Basalt

    Abstract: Energy losses due to excessive noise and heat are primary liabilities in traditional mining processes. Some of the currently researched methods to improve these liabilities involve heating the rock to induce internal stress fractures that make it easier to extract or remove rock with traditional mining equipment. Physical experimentation has yielded useful data that have been applied to numerical simulations of the heating and fracturing of rock, and multiple such simulations have been developed in the commercial multiphysics simulator COMSOL. Since COMSOL is not widely available on DoD high-performance computers, the goal of this research is to develop methods of replicating simulations developed in COMSOL as simulations that run in Abaqus FEA, another commercial multiphysics simulator. In this work, a simulated basalt cylinder with a 25 mm radius and a 158 mm height is subjected to a surface heat flux approximating the effects of a laser beam applied to the top of the cylinder. Simulated stress distributions, displacements, and temperatures obtained from both simulators are compared. When comparable results were not obtained using both simulators, the differences in results were investigated using simplified versions of the simulation.
