Simple Fatigue Example
Spreadsheet that performs a constant-amplitude fatigue crack growth analysis with numerical integration. A simplified trapezoid method is used that does not require iterative calculations.
Level 2 FAD
Macro-enabled spreadsheet (Excel + VBA) that performs fracture calculations with the API Level 2 failure assessment diagram (FAD) method. This tool is restricted to axial surface cracks in pressurized pipes.
Macro-enabled spreadsheet (Excel + VBA) that performs rainflow cycle counting on load versus time data. Data filtering, as illustrated in Figure 10.21 (4th Edition) is included. The output is the raw rainflow results, which consists of half cycles and full cycles. This tool does not create binned histograms.
API 579 Effective Area
Macro-enabled spreadsheet (Excel + VBA) that performs effective area calculations using the API 579 Level 2 metal loss assessment. The user input is a thickness grid. A remaining life calculator is included.
