Training: Design by Analysis for ASME Vessels in Practice
What does the ASME code demand of an FE analysis? Whether nozzle loads, wind and earthquake, load cycles or special constructions — FE analyses are used in many ways under ASME too. Besides building the model correctly, the ASME-compliant a...
What Topology Optimisation Does Not Give You
Topology optimisation has something seductive about it: you specify the design space, the loads and the boundary conditions, and the software delivers an organic-looking structure that leaves material exactly where it has to carry load. The result looks...
Safety Distances for Gas Flares: What Thermal Radiation Has to Do with It
A gas flare safely burns off residual gases — but in doing so it radiates considerable heat into its surroundings. How close may people, plant and neighbouring buildings come to a flare? This question is not left to feeling...
Response Spectrum over Time History: When the More Accurate Method Is Wrong
In earthquake analysis there is a case that runs counter to engineering instinct: sometimes the more accurate method is not the better one. Transient time-history analysis represents the earthquake step by step and is ther...
Four Ways to Assess a Weld — and When Each Fits
Verifying a weld by calculation is not a question of right or wrong but of the appropriate method. Several established concepts exist, and they differ considerably in effort, level of detail and the modelling they require. Choose the most expensive w...
