Standards catalog

Validation: indicative · Method band: formula

Indicative method: Indicative closed-form or numerical model

Linear elastic material behavior unless noted otherwise.
User is responsible for load combinations and load factors per the selected design code.

Does not replace a licensed professional engineer or official code compliance review.

Purpose: General reserve factor calculator for circular solid section under combined loading.

Method: Closed-form von Mises on circular shaft section:

σ_{v m} = σ_{n}^{2} + 3 (τ_{v}^{2} + τ_{t}^{2})

Outputs: yield and ultimate safety factors, governing limit.

Design codes: Indicative only.

UI: Legacy layout. No unit profile.

Gaps: Circular solid only; utility module — overlaps combined-loading/shafts.
