Influence of heat flux loading patterns on the surface cracking features of tungsten armor under ELM-like thermal shocks

•Mechanism of cracking on tungsten surface observed in high heat flux thermal shock tests is elucidated.•Representative cracking patterns under ELM-like loads are reproduced by progressive fracture simulation.•Driving force for crack extension is assessed for various crack configurations and loading...
