Delamination Risk with delamination severity score of 4 score: a worked example

This worked example runs the delamination risk numbers for a tougher week than the baseline: delamination severity score of 4 score instead of the typical 8 score. Estimate delamination risk priority for composite parts or bonded assemblies.

The inputs for this scenario

  • Delamination severity score: 4 score (the input this scenario stresses; the baseline uses 8)
  • Delamination occurrence score: 4 score (held at the documented default)
  • Delamination detection difficulty score: 5 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Delamination Risk = delamination severity score × delamination occurrence score × delamination detection difficulty score.
  • Delamination risk score works out to 4.25 score at these inputs, and this is the headline figure for the scenario.
  • delamination severity score works out to 4 score at these inputs.
  • delamination occurrence score works out to 4 score at these inputs.
  • delamination detection difficulty score works out to 5 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where delamination severity score sits at 8 score and the headline result is 5.85 score, this scenario comes in 27.35% below the baseline at 4.25 score.
  • Use it during process FMEAs, NCR root-cause reviews, or when prioritizing NDI and cure-process improvements across a family of composite parts. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Delamination risk score: 4.25 score (headline result)
