Endurance Limit (Marin Factors) Calculator

Calculate the corrected endurance limit S_e = S'_e × k_a × k_b × k_c × k_d × k_e × k_f using Marin modification factors for surface, size, load, temperature, reliability, and miscellaneous effects.

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

Calculate the corrected endurance limit S_e = S'_e × k_a × k_b × k_c × k_d × k_e × k_f using Marin modification factors for surface, size, load, temperature, reliability, and miscellaneous effects

Each component has a specific meaning:

  • Marin modification factors — The marin modification factors recorded for the patient or scenario being assessed.

Note: Interpret the endurance limit result against the clinical thresholds and context described above.

How to Use

Enter the Marin modification factors for the patient or scenario you are assessing. Calculate the corrected endurance limit S_e = S'_e × k_a × k_b × k_c × k_d × k_e × k_f using Marin modification factors for surface, size, load, temperature, reliability, and miscellaneous effects. Use the endurance limit result to inform your clinical assessment.
