Calculation method
Calculation method
Nominal flexural stress (MPa)
Symmetric two-nose loading, total force P: σ=3Pa/(bd²); center deflection=Pa(3L²−4a²)/(48EI), I=bd³/12.
Apparent flexural modulus (MPa)
Symmetric two-nose loading, total force P: σ=3Pa/(bd²); center deflection=Pa(3L²−4a²)/(48EI), I=bd³/12.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Symmetric two-nose loading, total force P: σ=3Pa/(bd²); center deflection=Pa(3L²−4a²)/(48EI), I=bd³/12. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
