文摘

Thermal shock fracture is studied using time-fractional heat conduction. Thermal stress intensity factors for edge and center cracks of a plate are derived. Super-, normal-, and sub-diffusion on the thermal stress intensity factors are discussed. Dangerous crack length and position are discussed for cold and hot shocks.
