Fatigue Finite Element Analysis

DMS offers a range of combinations for fatigue analysis and FEA.  We can utilize fatigue tools integrated with our FEA package, or perform the fatigue assessment separate from the FEA results.  This array of options allows us to customize the supporting science and deliver you the best results with the most efficient combination.

Finite element analysis (FEA) for fatigue holds great potential:  both to improve vessel life and to incur a high engineering cost.  Fatigue FEA really involves two analyses combined.

  1. Use FEA to determine the stress range at various critical points in the structure.
  2. Perform fatigue analysis to determine the expected life of each point.

Maybe you don’t need every weld point analyzed.  A typical fatigue FEA identifies dozens of potential fatigue sites.  But some are more important than others.  DMS will work with you to select only a few sites for full fatigue life predictions.  The remaining sites just get noted for inspections.  This focuses the maintenance and still improves your efficiency.  But at a lower engineering cost, and everyone wins.

Six Ways to Break the Ship

Why are ship structures so labor intensive to design? Engineers need to anticipate multiple methods of failure, which makes a lot of work. The trick of efficient structural analysis focuses on recognizing which methods of failure are likely in each scenario. This article reveals six major methods of structural failure, with examples of common applications. Because it will be the failure mode you didn’t consider that ultimately leads to catastrophe.

Improve Engineering Value

We all want to feel good about paying for engineering analysis. Sometimes the best answer drives us to maximize value, rather than minimize cost. In those cases, you do better to go beyond basic safety and search for enhancements. Today we discuss four engineering tasks where you can maximize your value. Extract every last drop of knowledge from your engineering project.
