Our talented team of engineers, physicists and computer scientists engages in research, development and testing for government agencies and private industry.
Our expertise includes nonlinear dynamic structural analysis, three-dimensional computational fluid dynamics (CFD), fire and thermal effects, structural acoustics, sonar, development of advanced analysis techniques and assessment of structures under blast loads. Our work addresses a variety of subjects within the areas of applied mechanics, applied mathematics, materials science and computational methods.
Much of our R&D work involves writing and maintaining computational software, and development of fast-running tools for modeling blast, shock and impact loadings. These tools can be used to analyze military and civilian structures subjected to terrorist and conventional weapons loadings both in air and underwater.
Our team has decades of experience in the development and analysis of ships and submarines and of the methods and criteria used to assess performance and qualification, for clients that include the U.S. Navy’s NAVSEA and ONR, NATO and the U.K. Royal Navy.
We also provide survivability and lethality assessments for land-based and buried structures subjected to nuclear or conventional weapons. Our expertise and computational tools support mission planning, test planning and performance, and prediction of effects and consequences of explosive events. These capabilities assist clients – the Defense Threat Reduction Agency, the Air Force and the Department of Homeland Security, among others – in fields such as weapons design, target defeat, building and infrastructure vulnerability, and structural hardening.
We operate test facilities, where we perform real-world testing to generate validation data for our modeling and simulation R&D and to conduct experimental R&D.
We maintain extensive instrumentation and diagnostic capabilities to underpin our testing services. These include the measurement of strain, velocity, acceleration and pressure for high-severity events; damage detection using modal techniques; and laser scanning to characterize damage on structures and equipment under test.
We apply our unique expertise to the following areas:
• UNDEX survivability, lethality and engineering support
• Airblast survivability, lethality and engineering support
• Fire and thermal effects on military platforms
• Shock testing: airgun, pond and deep-sea
• Structural acoustics and sonars
• Ship impact, collisions, grounding
• Fleet sustainment applications and repair
• Uncertainty quantification and reliability
