Finite Element Analysis (FEA)

Finite Element Analysis (FEA) can be an extremely powerful tool for design and optimization of ship structures . . . if you get it right.  FEA allows us to analyze any array of complex structures.  That freedom brings new designs and reduced structure weight.  We don’t simplify the structure just to make the math easier.  Structures get designed for performance, like you expect from high value engineering.

FEA allows us to explore a nearly limitless range of structural design options.

  • Foundation design for large equipment
  • Global structural strength
  • Loading of unique cargo and deck strength
  • Thermal expansion checks
  • Design of unique structural shapes
  • Design of critical weld joints
  • Weight reduction of large beam segments
  • Fatigue analysis for vessel life extension
  • Composite materials design
  • Forensic engineering
  • So much more . . .

At DMS, we prove the accuracy of our FEA.  We perform independent FEA validation studies.  This compares FEA models to known real world experiments.  The result is quantifiable accuracy of our FEA modeling capabilities.  Because quality results depend less on the tool than on the person who uses it.

For your actual project, we also perform mesh independence studies on each FEA model, further confirming the accuracy.  With DMS, you gain absolute confidence that the computer predictions match reality.

Video: Selecting the Right Hullform

Monohull, catamaran, trimaran . . . so many choices. Which hullform to pick? Can we draw upon any science to guide our choices, or we beg Lady Luck to guide us? This article provides a rational and design map for selecting hullforms applicable to any type of mission. This organized approach allows us to see past the limitations of historic examples and consider new alternatives.
