Shaft Design (ASME DE-Goodman) Calculator

Size a shaft under combined bending and torsion using ASME DE-Goodman: d = (16/π × [(KM/σ_e)² + (KT/τ_e)²]^(1/2))^(1/3). Includes stress concentration factors for fatigue.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Size a shaft under combined bending and torsion using ASME DE-Goodman: d = (16/π × [(KM/σ_e)² + (KT/τ_e)²]^(1/2))^(1/3). Includes stress concentration factors for fatigue

Each component has a specific meaning:

  • ASME DE-Goodman: d = ² + ²]^)^ — The asme de-goodman: d = ² + ²]^)^ recorded for the patient or scenario being assessed.

Note: Interpret the shaft design result against the clinical thresholds and context described above.

How to Use

Enter the ASME DE-Goodman: d = ² + ²]^)^ for the patient or scenario you are assessing. Size a shaft under combined bending and torsion using ASME DE-Goodman: d = (16/π × [(KM/σ_e)² + (KT/τ_e)²]^(1/2))^(1/3). Includes stress concentration factors for fatigue. Use the shaft design result to inform your clinical assessment.
