Multi-component residual stress profiling in thick sections
Deep Hole drilling is used to measure bulk residual stress in thick sections. The method can be applied to generate a residual stress profile through the thickness of large parts. Deep Hole drilling is typically performed in the laboratory, but can be applied in the field. Hill Engineering works with Veqter Ltd. to provide deep hole drilling services to our clients.
Deep Hole drilling is useful for
- Measuring a profile of the bulk residual stress in thick sections
- Applications requiring in-field measurements with portable equipment
- Measuring multiple stress components (in-plane principal stresses)
- Parts with large or complex geometry
