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.

When performing parametric structural analysis, ESRD’s p-element StressCheck FEA software is always my preferred choice due to the excellent solution quality, parametric framework, and superior computational efficiency. In fact, I recently used StressCheck to generate stress intensity factors along a parametrically defined elliptical crack-tip across 3,000 unique geometric configurations. Considering multi-body contact was present and all simulations were performed using a laptop, this was a task well suited for StressCheck.
