Done over 17 days, these 3 projects form a progression. Various objectives were served:
The three projects:
First working on 22nd January 2021; able to take every sample breaking abruptly at highest load reached - tough unrestricted-application
Conveying the more human story intertwining the technical story in an overview and path of the late 2020 / early 2021 series of mini-programmes
Application of Finite Element Analysis (FEA) modelling - representing in a parallel universe of theory and numbers FEA of the beam-configuration fillet-weld tensile test
Just modelled and not carefully considered yet - so presented advisedly - 3-D FEA of the BCFWTT weld area .
Fillet welds are an interesting topic because the designer is free to specify size, and other features, while the optimal choice does not inherently "suggest itself". They are economical and reliable to make, so understanding them by investigation can present good engineering choices.
Findings and analysis for fillet welds
In January 2021, I present
Proposal : research path to high-strength steel fatigue-resistant welded structures
which seeks a host for this investigative programme aiming to make use
of the observation that fillet welds can show fatigue resistances
approaching those of the steels they are joining.
Use of Euler-Bernoulli beam calculations for structures.
