Compressor Disk Spin Test

Crack growth from a bolt hole in a disk model

This example shows the growth of an initially quarter circular corner crack from a bolt hole in a gas turbine compressor disk. The analysis simulates a spin test. The crack grows to a through crack then advances into the structure. The analysis shown below is a single Zencrack analysis in which the initial corner crack grows through the thickness and continues as a through crack. The analysis shown was carried out using Zencrack 7.8-1 with Abaqus 6.12-1.

The analysis is based on data in the first reference listed below. More detailed discussion of the analysis, including the issue of gross plasticity at the bolt hole, is contained in the second reference listed below.

The animations below use displaced plots to help highlight the crack development.
