FEA For Marine

Structural Design and Analysis, Inc. (SDA) specializes in the design and analysis of lightweight, load-efficient composite structures. Our composite knowledge has been instrumental in the design of sport craft, racing yachts, and pleasure boats.

  • Structure Layout and Design
  • Primary Structure Sizing
  • Structure Layup Schedules
  • Independent Design Review
  • Material Selection
  • Manufacturing Methods
  • Strength Testing Support
  • Interpretation of Results
  • Failure Investigations
  • Analysis Reporting

Basic structural analysis is performed using classical hand analysis supplemented with NASTRAN Finite Element Analysis and Hypersizer Optimization. Finite Element capabilities include:

  • Statics
  • Normal Modes
  • Buckling
  • Geometric Non-Linear (Large Displacement)
  • Material Non-Linear
  • Non-Linear Transient Response
  • Contact Stresses

SDA also provides software solutions from Siemens PLM software for companies in the Marine and Shipbuilding industry.

Our customers range from large international shipbuilders like Gibbs & Cox and CDI Marine to SMBs like Ariston Technologies and Farrell and Norton Naval Architects.

We offer maintenance, technical support, and training for all our software customers.

Software offerings:

  • Femap with NX Nastran
  • Fibersim
  • NX CAD and CAE
  • Simcenter
  • Solid Edge

Femap with NX Nastran For Marine

We created this webinar for one of our marine customers. It covers how to spread loads on your model using data surfaces through the Data Surface Editor.

You'll learn:

  • What is load spreading?
  • How external data, such as a pressure map, can be imported into FEMAP and applied to your model as a pressure load.
  • How pressure plots can be made to compare to the external data.
  • Performing load summation to show how well the loads match the provided data.
