Corrosion, Fatigue & Failure

Why things break. Electrochemical corrosion and protection, fatigue, fracture mechanics, creep and failure analysis.

• Corrosion, Degradation & Protection — Why metals return to their ores — and how to stop them. Learn electrochemical corrosion (anodic and cathodic reactions), electrode potentials and the Nernst equation, the galvanic series and galvanic corrosion, Pourbaix diagrams, corrosion rate from current density (Faraday), forms of corrosion (uniform, pitting, crevice, intergranular, stress-corrosion cracking, erosion, microbial), passivity and stainless steels, high-temperature oxidation, polymer and ceramic degradation, and protection (materials selection, coatings, galvanising, cathodic protection, inhibitors, design) — with Python for Nernst potentials, corrosion rate and anode life.
• Fatigue — Fatigue is failure under repeated loading at stresses below yield. Learn S–N curves, endurance limit, mean-stress effects (Goodman), Marin factors, crack growth and how to design for millions of cycles.
• Fracture, Fatigue, Creep & Failure Analysis — Why things break — and how to prevent it. Learn ductile vs brittle fracture and fracture surfaces, stress concentrations, linear-elastic fracture mechanics (stress intensity factor K, fracture toughness K_IC, critical crack size, leak-before-break), fatigue (S–N curves, endurance limit, mean-stress effects, Paris-law crack growth, beach marks), creep (stages, Larson–Miller parameter), wear, and the failure analysis methodology (evidence, fractography, metallography, root cause) — with Python for critical crack size, Paris-law fatigue life and creep rupture life.
