The new software is an add-on customization for ABAQUS that supports the Dynamic Design Analysis Method (DDAM). Developed by the U.S. Navy, the DDAM is an analytical procedure that has been used for over 30 years to help validate the design of shock-sensitive equipment and structures for naval applications. Compliance standards for DDAM analysis are maintained by the Naval Sea Systems Command (NAVSEA).
Advanced simulation for underwater explosion (UNDEX) and other structural and acoustics analyses have opened new approaches to simulation of shipboard shock response. Interactive DDAM for ABAQUS allows marine engineers to perform the DDAM using ABAQUS; software provides DDAM-specific input forms through a graphical user interface as well as specialized DDAM output data. Engineers can also use DDAM for ABAQUS in batch mode to easily repeat DDAM analysis on different models and to automate creation of reports for design review.
DDAM for ABAQUS is provided free of charge to ABAQUS users; downloading instructions are available at www.abaqus.com/ddam.
