Sensitivity Analysis of the Inherent Strain Approach for the Buckling of a Thin Structure

The October 2024 issue of NAFEMS Benchmark Magazine features a benchmark example that compares experimental measurements and numerical simulations of a powder bed fusion (PBF) thin structure.

Using the inherent strain approach on the same benchmark component, TWI have systematically examined the influence of mesh refinement, element types, boundary conditions, and material and geometry assumptions. Their results will give attendees a unique insight into the work, and may change the way you approach your PBF simulations.

T​his exclusive NAFEMS webinar features the simulation engineers who carried out much of the work, presenting their findings clearly through comparison tables and visual contour plots.

The results will help you decide;

• Which numerical parameters actually matter in simulations like these?
• Where can I safely simplify my model?
• What's the trade-off between computational cost and model fidelity?
