Application of anhysteresis residual magnetization method to evaluate distribution of additional plastic deformation in ferromagnetic metals

After a huge earthquake, it is important to evaluate additional plastic deformation induced by the disaster to identify damage to important structures such as nuclear power plants, tall buildings, or high-pressure hydrogen infrastructure. As residual magnetization takes on anhysteresis characteristi...
