My generation of Structural Engineers (graduated in the early ’90s of last century) in the mechanical field were post-pioneers in computation with Finite Elements. I say this because they found themselves operating in an industrial environment that was not at all ready to include in the design cycle a phase whose usefulness entrepreneurs struggled to […]
Fatigue assessments are never an easy task, but they are not impossible. FE results on one side give a bunch of information that might confuse and on the other pose questions on both the notch sensitivity and dimensional coefficients. In Chapter 10 of the book “Computational Structural Engineering” the reader is guided through all those […]
In Chapter 17 of the book “Computational Structural Engineering” a very deep analysis of a “simple” bolted connection is presented: influence of preload and friction are discussed and failure is simulated. Finally, a comparison between the implicit and explicit approaches (which are discussed in Chapter 14) is also presented.https://www.cgcae.com/wp-content/uploads/2024/10/Boltfailure.mp4
Here is one case where axisymmetric elements can give great results in very short times, even when dealing with hyperelastic materials! In this case an O-Ring is stretched into its position (this phase is not reported here, but maybe in a future post it will) and then the outer tube is pushed to assemble the […]
