I am often asked to comment on how it is possible that, although everybody agrees simulation governance is a good idea, it is not being practiced — or, as Shakespeare would put it more elegantly, “more honour’d in the breach than the observance.” — The short answer is that changing minds and habits is hard. A more detailed explanation follows.
Anyone who relies on information generated through numerical simulation must know the difference between calibration and tuning, and understand the interactions between finite element modeling and finite element analysis. This blog post covers the main points.
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.”
