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.

“Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”
