ASM Handbooks has published a new chapter in Residual Stress Fundamentals, Volume 25A: The Contour Method for 2D Residual Stress Mapping. Authored by Michael Prime and Hill Engineering’s own Adrian DeWald, the chapter delivers an in-depth exploration of one of our most powerful and popular residual stress measurement techniques.
Below is the abstract text:
This article presents the ideal theoretical implementation of the contour method – a residual stress measurement technique well suited to quantify bulk residual stress. It describes the measurement of additional stresses using multiple cuts or multiple methods and superposition. It explores near-surface/wedge uncertainties and sacrificial layers along with cut sequencing strategies to minimize plasticity and bulge errors. The article also outlines fracture surface contour and the Eigenstrain-based analysis to simplify the analysis of residual stress fields.
For engineers seeking a fundamental understanding of the contour method, this chapter provides both the theoretical basis for the technique as well as applicable use cases within industry.
