COMSOL Tutorial: Stress Concentration Factor | Plane Stress & Parametric Sweep!

COMSOL Tutorial: Stress Concentration Factor of a Plate | Plane Stress & Parametric Sweep In this tutorial, you’ll learn how to calculate the Stress Concentration Factor (Kt) of a thin rectangular plate with a central circular hole using the Solid Mechanics interface in COMSOL Multiphysics. The model uses the Plane Stress formulation and symmetry boundary conditions to reduce the computational cost. 📌 What You’ll Learn: ✅ Modeling a thin plate with a central circular hole ✅ Applying Plane Stress formulation for thin structures ✅ Using symmetry boundary conditions to model only one quarter of the geometry ✅ Applying structural boundary loads correctly ✅ Using Parametric Sweep to vary the hole diameter ✅ Using Table Graph ✅ Calculating the stress concentration factor (Kt) Stress concentration analysis is an important topic in solid mechanics and mechanical design. This tutorial demonstrates how finite element analysis (FEA) can be used to accurately predict stress amplification near geometric discontinuities such as holes and fillets. 📚 Reference Book: Shigley’s Mechanical Engineering Design by Richard G.
