4.1 Shaft Design (shafts)

Purpose: Rotating shaft under combined torque, bending, and optional axial load — stress, deflection, critical speed.

Method: FEM — 1D shaft elements with torsion and bending DOF; post-processing for von Mises, critical speed estimate.

Key outputs: $\tau_{max}$, $\sigma_b$, $\sigma_{vm}$, deflection curve, critical speed margin.

Design codes: Indicative combined stress, deflection, critical speed (AGMA 6001 / DIN 743 referenced in catalog, not fully implemented as code checks).

UI: Modern inputs/results; region unit sync; mesh control. Featured module.

Gaps: Uniform diameter shaft; fixed-end boundary; fatigue screening not integrated; high refactor risk.

Maintainer note: Mechanics + fatigue pipeline with many derived parameters.
