DNVGL RP C203 Fatigue System Effect

Calculate DNVGL-RP-C203 system effect factor.

The system effect factor accounts for uncertainties where a number of identical joints are being checked (for example an anchor chain).

CALCULATOR : DNVGL RP C203 Section F.5 System Effect Factor [FREE]   ±

Calculate fatigue stress system effect factor (DNVGL-RP-C203 section F.5).

The system effect factor accounts for the statistical variation in test samples, and actual load cases. The standard SN curves include an allowance for standard deviation (mean minus two standard deviations).

Tool Input

  • devtype : Standard Deviation Type
    • Slognu : User Defined Standard Deviation Of log N
  • systype : System Effect Factor Type
    • nsu : User Defined Number Of Connections
  • Lweld : Weld Length
  • Lref : Reference Length

Tool Output

  • Rs : Sytem Effect Factor
  • Slogn : Standard Deviation
