The SDASL Lab attended the 32nd International Modal Analysis Conference where six students presented 10 papers. The papers ranged from a variety of topics on current student research related to both funded and unfunded projects for the DOE & NSF on Wind Turbine Structural Health Monitoring, Eglin Air Force on Nonlinear Response Analysis, NSF Sustainable Energy Pathway for Wind Turbine Blade Manufacturing as well as additional work related to Capstone Design Shock Response Spectrum support projects and ongoing optical correlation methodologies. The students did a great job presenting the material and many well-known seasoned conference attendees noted the high caliber of work going on at the university as well as the very professional presentations that were made.

This is yet another successful SDASL conference outing that continues to showcase the outstanding work being done here at UMass Lowell. The group pictured at one of the IMAC Conference events showing several UML SDASL students, very recent graduates and alumni.
