Adaptive Optics Strehl Ratio Calculator

Calculate Strehl ratio from wavefront RMS error using the Maréchal approximation. Determine adaptive optics correction requirements for diffraction-limited performance.

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.
