Pressure Vessel Design: Validating ASME Analytical Solutions vs. Ansys FEA (PART 2)

In Part 1, we established the geometric foundation and the "why" behind the 8.33 mm cylinder and 4.17 mm hemispherical head thicknesses. Now, we dive into the Main Analysis. In this video, we move beyond the CAD and into the physics of Ansys Mechanical. We aren't just looking for colorful plots—we are validating our ASME analytical solutions against Finite Element Analysis (FEA) results. What you’ll learn in this session: Physics Setup: Applying internal pressure and defining boundary conditions (Symmetry & Frictionless Supports).Stress Interpretation: Why the Max Principal Stress is your best friend for validating Hoop Stress (sigma theta). The "Spike": Identifying and justifying the 170MPa discontinuity stress at the junction that your hand calcs missed. Result Validation: Comparing the 119.3 MPa FEA result to our 120 MPa design target. Pro-Level Probing: How to extract Axial, Circumferential, and Von Mises stresses to justify your design.
