Numerical Integration
Engineering Fundamentals · Last updated: July 30, 2026 · How this entry was written
Definition: Numerical integration is a method for approximating the definite integral of a function using discrete data points when an analytic antiderivative is unavailable or impractical.
Example in context
“The stress distribution along the beam was computed using numerical integration of the measured strain data.”
“Kiriş boyunca gerilme dağılımı, ölçülen gerinim verilerinin sayısal entegrasyonu kullanılarak hesaplandı.”
Where engineers use it
Used when solving integrals of complex functions in finite element analysis, heat transfer, or fluid dynamics. Engineers rely on it to obtain approximate solutions where exact analytic integration is impossible or inefficient.
Synonyms: quadrature, approximate integration
Antonyms: analytic integration
Practice: can you use “Numerical Integration” at work?
You are evaluating a curved plate's deflection under a load where the moment equation cannot be integrated analytically. Compute the deflection using a suitable numerical integration method.
