► Residual stresses dominate the overall performance of mini-plates. ► Thermo-elasto-plastic material model with thermal creep was formulated. ► Fuel foil is exposed to compression, while cladding is exposed to tensile field. ► Even though fuel stays below its yield limit, cladding material exhibits...
