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.

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
