Hierarchic Approaches to Modeling Fastened Connections Webinar

Strategies in engineering simulation for reducing the frequency, cost, complexity, and uncertainty of aircraft maintenance inspection intervals.

This webinar will focus on best practices for accurately modeling & analyzing fastened connections and joints, including appropriate simplifying assumptions based on the data of interest.

Hierarchic modeling of fastened connections, including Planar-only (fastener + link + 2D elements), multi-body contact (load transfer between all parts), plug/partial contact (load transfer between notable parts), & normal springs (compression-only single part analysis) approaches.
Pros, cons and applicability of each hierarchic approach will be analyzed.
CASE STUDY: 3D Lug Comparison – Multi-body contact, plug/partial contact & normal springs.
LIVE DEMO: You will learn the process of checking reactions in contact regions/holes, as well as how to perform live-dynamic processing of detailed stresses in multi-part assemblies.

“Through the use of StressCheck the A-10 Aircraft Structural Integrity Program’s (ASIP) Analysis Group is able to model more accurately the physics of fatigue crack propagation in critical aircraft structure. Through this tool we are able to model, analyze and predict failure of aircraft structure and then develop crucial inspection and maintenance planes to ensure the safety and sustainability of our nations warplanes. Without the analysis capability provided to us through StressCheck we would not be able to provide accurate assessments of the A-10 structure to top USAF leadership.”
