ASIP 2018 Training – Modeling Fastened Connections: Hierarchic Approaches Discussion and Demo
Abstract: This 2-hour training course will discuss a hierarchic approach to modeling fastened joints using Finite element Analysis (FEA) with specific examples and case studies using professional FEA software. Model conceptualization, including all simplifying assumptions based on both the available information and the data of interest will be covered as well.
Originally presented as a training course at the 2018 ASIP conference in Phoenix, AZ.

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”
