DDAM Analysis with Abaqus
Objective:
The Dynamic Design Analysis Method (DDAM) is a U.S. Navy developed analytical procedure
for evaluating the design of shock-sensitive equipment and structures for naval applications.
DDAM for Abaqus is an add-on customization for Abaqus that allows marine engineers to
efficiently implement the DDAM. The add-on provides DDAM-specific input forms and generates
specialized DDAM output. It can be run interactively via a graphical user interface or in a
background batch mode.
This course details the DDAM for Abaqus procedures for performing the DDAM shock
response calculations and provides the student with hands-on experience via representative workshops.
The topics covered include:
- Introduction to the DDAM
- Overview of the DDAM for Abaqus Approach to Shock Response Analysis
- Shock Spectra Calculations (NRL-1396, User Inputs, Direction of Attack)
- Orienting the Finite Element Model with Respect to Ship Axes
- Using Automatic and Manual Mode Selection Criteria
- Nodal Acceleration Check for Mode Selection
- Closed Form Treatment (NAVSEA 3010) approach to Closely Spaced Modes
- Summation of Beam and Shell Stresses (Membrane, Membrane + Bending)
- Options for Averaging Shock Response Results
- Combining Operational Load and Shock Response Results
- Automated Generation of DDAM Model and Shock Response Data
The workshops include:
- Defining Shock Spectrums
- Creating a DDAM Model (Pump Assembly on a Hull Mounted Box Girder)
- Generating and Viewing Intermediate Results
- Generating and Viewing DDAM Shock Response Results
- Evaluating Closely Spaced Modes for a Pump-Shaft Model
Who should attend:
This course is recommended for engineers with
experience using Abaqus. Some familiarity with Abaqus/Viewer is recommended.
