Study transient thermal stress in a ventilated brake disc. • Outer diameter: 0.3 m. • Ventilation channels: 10 radial slots (5 mm width). Material: Gray Cast Iron (E = 120 GPa, ν = 0.28, k = 50 W/m•K). Boundary Conditions: • Heat generation: 800°C surface temperature (5-second braking). • Convective cooling (h = 30 W/m²•K) post-braking. Analysis Steps (SimScale): 1. Transient thermal analysis (20-second simulation). 2. Coupled thermo-mechanical stress analysis. 3. Mesh refinement near ventilation channels. Deliverables: • Temperature-time history at critical points. • Von Mises stress distribution during heating/cooling. • Identification of crack-prone zones.
