An ALERT Short Course, Dynamic Compression & Fracture of Materials

AUG. 17-21, 2009 AT NORTHEASTERN UNIVERSITY

Understanding and modeling the response of materials to dynamic loading, characterized by high stresses and short time scales, is central to mitigation strategies against explosive loading and/or high velocity fragment impacts. A unique feature of material fracture under dynamic loading is that compression always precedes tension. Hence, understanding material response under both dynamic compression and tension is important. This course has been developed to provide the attendees a comprehensive learning experience regarding the dynamic compression and fracture of materials. The course will consist of three main elements: fundamentals of large amplitude stress wave propagation (60 percent); use of pulsed power drivers for achieving shock wave and shockless compression (20 percent); dynamic fracture (20 percent). Each part will be taught by an expert possessing a strong in-depth understanding of the subject material. The course will emphasize fundamentals, contemporary developments, and future challenges. Significant time will be set aside for discussion between the speakers and the attendees. The course content will be at the level of a graduate course in physical sciences and engineering.

The short course will be taught by Prof. Y.M. Gupta of Washington State University, with guest lecturers Dr. M.D. Knudson of Sandia National Laboratory and Dr. G.T. Gray of Los Alamos National Laboratory.

To register for this course or for further information, contact Mariah Nobrega at 617-373-3031 or mnobrega at coe.neu.edu

ALERT Researchers Win Multi-million Dollar Grant to Develop Critical Infrastructure Sensing Technology

Northeastern University has been awarded a $9 million federal research grant to develop new multi-sensor technology systems for cars and trucks that will allow for real-time assessment of road and bridge infrastructure across the country. Northeastern will lead the five-year VOTERS (Versatile Onboard Traffic Embedded Roaming Sensors) project along with a range of government, industry, and academic partners. Read Article...

 

 

STATEMENT OF CONGRESSMAN EDWARD J. MARKEY (D-MA) IN RECOGNITION OF NORTHEASTERN UNIVERSITY'S LEADERSHIP OF ALERT PROGRAM:

"As a member of the House Committee on Homeland Security and longstanding advocate of improved explosive detection technologies, I am proud of the contributions that academic research institutions including Northeastern University are making to counter explosive-related threats. Northeastern's designation as a Center of Excellence by the Department ofHomeland Security is particularly impressive, and it recognizes the university's leadership and strength in the field of sensing and imaging. I look forward to seeing the results of this vital research, which could lead to important advances in our country's ability to thwart attacks involving explosives and mitigate damage if such attacks do occur." - October 30, 2008.

 

 

DHS Center of Excellence Ribbon Cutting at the Gordon-CenSSIS RICC

The launching of the new Department of Homeland Security Center of Excellence for Awareness and Localization of Explosives-Related Threats (ALERT) took place during the Gordon-CenSSIS Research & Industrial Collaboration Conference (RICC), on October 29-30, 2008, at Northeastern University in Boston, MA
