Abstract

A new approach to analyze fastener joints loaded with out-of-plane forces and moments was introduced in Reference 1. This article discusses the results of eight (8) fastener joints analyzed using the proposed analysis approach as compared to the results of idealized finite element models that were constructed to simulate the properties and behavior of these joints. The fastener joints analyzed entail six (6) low to medium aspect ratio joints and two (2) high aspect ratio joints. Results of the idealized finite element models are within ±10% of the results of the proposed analysis approach.
