Simplified Fatigue Analysis with 2 Segment S-N Curves (ABS) - (www.thenavalarch.com)

Hi

thenavalarch launches a new product: Spreadsheet app for Fatigue Analysis of Offshore Structures

This program can be used to assess the Fatigue Strength of an Offshore Structure based on ABS GUIDE FOR ” FATIGUE ASSESSMENT OF OFFSHORE STRUCTURE” with 2 -segment S-N Curve

The calculation is done based on the simplified approach that the linear cumulative damage (Palmgren-Miner) rule applies, and that fatigue strength is defined by the S-N curves.
The other underlying assumption is that based on the long-term distribution of stress range,
a closed form expression for fatigue damage can be derived.
User is required to provide some basic fatigue inputs, create load cases and provide inputs specific to load cases.
The application calculates the individual and cumulative fatigue damages and generates a detailed report too.
