StressCheck Tutorial: Mapping Cold Working Residual Stresses to a Reamed Part via BRS Method
Abstract: Mapping residual stresses generated by cold working to a reamed part via Bulk Residual Stress (BRS) mapping and loading methods. Using Solution Configurations + Parts and the StressCheck BRS Module to:
- Solve a Cold Working (CX) analysis via Incremental theory of plasticity and Nonlinear Events
- Map the post-CX residual stress distribution to the reamed part using BRS mapping
- Apply the BRS-mapped stress distribution to the reamed part as a new load case
- Solve for stress redistribution in the reamed part.

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”
