Скачать или смотреть Stress Concentration Factor (Contd.)

This channel provides a deeper explanation of the *Stress Concentration Factor (Kₜ)* and its application in fatigue and structural analysis. It clarifies how Kₜ is defined with respect to **gross (nominal) stress and net-section stress**, and how local stress amplification develops around geometric discontinuities.

The content covers:

Distinction between *Kₜ based on gross stress* and *Kₜ based on net stress*
Stress distribution around *holes, notches, and filleted regions*
Use of *stress concentration charts and empirical relations* for common geometries
Influence of geometry parameters (hole size, width, radius) on peak stress
Sensitivity of *anisotropic materials (e.g., composites)* to notches and stress concentrations

The channel is intended for *engineering students, fatigue analysts, and design engineers* seeking a clear and application-oriented understanding of **stress concentration effects**, essential for fatigue life prediction, notch-sensitive materials, and safe structural design.
