  • Out-of-season outage closes The Dalles Dam navigation lock

    An out-of-season outage will close The Dalles Dam’s navigation lock, Sept. 14-15, 2021. A specialized U.S. Army Corps of Engineers rope-access (climbing) inspection team will be performing an assessment, which is part of a required five-year cycle.

  • Energy savings virtual workshop sees attendance nearly double

    The workshop assists in helping the Army achieve mission effectiveness and achieve mandates imposed by laws and Department of Defense regulations by integrating energy programs, initiatives and activities.

  • NR 21-31: Corps of Engineers soliciting proposals for development of Cook Recreation Area at J. Percy Priest Lake

    NASHVILLE, Tenn. (Sept. 9, 2021) – The U.S. Army Corps of Engineers Nashville District is soliciting proposals for operation and maintenance of multipurpose recreational facilities, which include a campground and related facilities and services at the Cook Recreation Area on J. Percy Priest Lake in Hermitage, Tennessee. Proposals will be accepted through Jan. 10, 2022.

  • A call to serve: One Soldier remembers 9/11

    On Sept. 10, 2001, Maj. Jarrod Gillespie, who now serves as deputy chief of contracting at the U.S. Army Engineer Research and Development Center (ERDC), was a junior at Alcorn State University in Mississippi. He enlisted in the Army Reserves right out of high school, and while he enjoyed being a Soldier, his plan was to graduate from Alcorn State, finish his military service and begin civilian life as a culinary arts student with plans to open his own restaurant. The next day, everything changed.

  • Shear and Tensile Delamination of Ice from Surfaces: The Ice Adhesion Peel Test (IAPT)

    ABSTRACT: For decades, researchers have sought to understand the adhesion of ice to surfaces so that low-cost ice mitigation strategies can be developed. Presently, the field of ice adhesion is still without formal standards for performing ice adhesion tests. The U.S. Army Corps Engineers’ Research and Development Center’s Cold Regions Research and Engineering Laboratory (ERDC-CRREL) has a longstanding history as an independent third party for ice adhesion testing services. Most notably, CRREL’s Zero-Degree Cone Test (ZDCT) has been an industry favorite for more than 30 years. Despite its wide acceptance, the ZDCT contains some shortcomings, namely that freshwater ice is formed on the surface of interest within the confines of an annular gap. To address this limitation, CRREL developed and uses the Ice Adhesion Peel Test (IAPT) for testing ice adhesion. This test employs an open planar substrate from which the ice can be removed under either tensile or shear loading, thereby allowing ice to be grown directly on the target substrate without the use of molds. The IAPT configuration is therefore amenable to different ice types and geometries and will provide utility to research studies that aim to develop surface treatments to mitigate ice in a wide range of environments. This report describes the IAPT and its use for characterizing the ice adhesion properties of materials.
