Euler Buckling Load Calculator

Calculate critical buckling load: P_cr = π²EI/(KL)². Critical stress σ_cr = P_cr/A = π²E/λ². Applies for elastic buckling where σ_cr < 0.5F_y. Inelastic range uses tangent modulus theory.

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 to Use

Enter the values for the patient or scenario you are assessing. Calculate critical buckling load: P_cr = π²EI/(KL)². Critical stress σ_cr = P_cr/A = π²E/λ². Applies for elastic buckling where σ_cr < 0.5F_y. Inelastic range uses tangent modulus theory. Use the euler buckling result to inform your clinical assessment.
