StressCheck Demo: 2D Fastened Joint Analysis
Abstract: A 2D Fastened Joint Analysis Demo video is presented for a splice joint. StressCheck fastener and link elements are used to fill holes and connect the splice plates for the Planar model, linear and general nonlinear analysis are performed, and the load transfer to each fastener element is extracted from the general nonlinear solution.

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.”
