Hierarchic Approaches to Modeling Fastened Connections Webinar
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.
WEBINAR HIGHLIGHTS
- 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.

“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”
