Research and Education Horizons
The Damage Science & Mechanics (DS&M) Laboratory pursues research and educational activities which are often at or over the horizon. Often research funding for these areas will not be recognized as a priority for a number of years into the future. By championing such activities it is possible to influence the philosophical underpinnings which ultimately serve as the foundation when more widespread recognition of the importance of these areas occurs. The approach is to educate students and others in the scientific and engineering communities as well regarding these issues deemed important.
Sustainable Design - SD offers a coherent means of discussing a number of DS&M Laboratory research focus areas.
NDE Engineering - John Duke has been a pioneer in advocating for Nondestructive Evaluation Engineering (NDE) as a disciplinary expertise area essential to planning and design teams, observing that these areas embrace not only nondestructive inspection technology and methodologies and also materials durability and performance assessment in the presence of deterioration. Dr. Duke served as the representative of the American Society for Nondestructive Testing, Inc. as their official observer at the ABET BOD meeting during a time when ASNT was promoting a possible NDE Engineering undergraduate degree.
NDE for Additive Manufacturing - Often when new materials or manufacturing approaches are developed there is a need, but also a hesitancy to assess the quality of the prototypes. Parts made using additive manufacturing pose challenges because the materials of the finish part did not exist in that state before the part was created. Traditional approaches for assessing the properties and performance of materials involves creating test samples of simple geometry. In that properties and performance might be influenced by both the geometry and the creation process the traditional approach seems ill-suited. Nondestructive materials and performance characterization are appropriate for this application.
Structural Health Monitoring (SHM) for detecting end of functional-service-life - In order to remove critical systems and structures from service before the end of service-life it is necessary to detect the end of functional-service-life. Laboratory research as well as application to actual systems and structures entails defining strategies which can be practically implemented; this a persistent thrust of the DS&M Laboratory.
Low-cost UAV augmented under bridge visual inspection - A BEAM senior project design group under Dr. Duke’s guidance designed a system which can reduce the costs by guiding the detailed arms-length inspection of transportation structures.
