Load Application Review Checklist
Review prompts for load application — physical load paths, distributed versus point loads, bearing loads, inertial loads and load verification.
Purpose
For checking how loads are applied to an FE model before accepting results.
Load Path
- Do loads enter the model through the same path as they enter the real structure? — Load introduction determines the stress distribution
- Are concentrated loads distributed over a small surface using coupling or pressure? — Single-node point loads create singularities
- Are bearing loads applied using a bearing formulation, not uniform pressure on a full hole? — Half-cylinder pressure is more realistic
- Are bolt preloads applied through bolt elements or preload sections? — Not as a force on the hole surface
Inertial and Body Loads
- Are inertial loads applied as acceleration or gravity body forces? — Not as equivalent nodal forces
- Is the mass distribution correct — including non-structural mass? — Bolts, sealant, equipment, fuel
- Is the centre of gravity consistent with the design definition? — Check model mass properties
Load Verification
- Do applied loads match the approved loads report? — Magnitude, direction and distribution
- Do reaction forces balance applied loads to within 1% in each direction? — The most fundamental equilibrium check
- Is the load introduction region free from stress singularities? — Check deformed shape near load point
- For multiple load cases, has each been run and verified individually? — Before combining or enveloping
