Analysis & Test

Welcome to the ERSI Analysis & Test committee website. A list of the current and previous round robin activities are listed below, along with all the associated files available for download.

Stress Intensity Factor Round Robin (2021)
Objective: The primary objective of the Stress Intensity Factor (SIF) round robin was to evaluate differences between available SIF solutions for a single corner crack at a fastener hole with remote uniform tension loading. The evaluations included not only the root SIF solution but any corrections to account for single vs multiple cracks, finite width, and hole offset. These solutions were compared to explicit Finite Element Analysis (FEA) results of each case. Any findings were intended to drive improvements to solutions available to the fracture mechanics community.
