Smart-substrate: a novel structural design to avert residual stress accretion in directed energy deposition additive manufacturing

Residual stresses, related distortions and cracks are detrimental in metallic Additive Manufacturing (AM).Previously developed stress-control strategies based on reducing thermal gradients hardly diminish the stress concentrations at the built basement and easily affect other physical phenomena involved in AM.To overcome this, a novel strategy, nam
