Kakaliagos et alii, Frattura ed Integrità Strutturale, 50 (2019) 481-496; DOI: 10.3221/IGF-ESIS.50.40 496 temperature induced residual plastic deformations, which in turn could produce residual stresses in the chamber. As the gun crew tried to cool the bombard within a short period of time, residual stresses were potentially increased. Successive firing of the bombard resulted in a continuous deterioration of powder chamber structural response. R EFERENCES [1] Barbaro, P.V., Niccolò (1856).
