Discover why pressure vessels fail where calculations stop — even with flawless ASME formulas, hand calculations, and advanced FEA models. This episode exposes the real-world blind spots in mechanical engineering: undetected fatigue cracks from cyclic loading, corrosion and erosion that codes underestimate, weld residual stresses, material variability, fabrication tolerances, and unpredicted operational transients that turn theoretically safe designs into catastrophic ruptures.
