Experimental and numerical aspects of ship structure failure under airblast loading

This work aims at studying experimentally and reproducing numerically the failure mechanisms of a ship structure material when submitted to severe conditions of strain and strain rate. Laboratory tests and airblast experiments were accordingly carried out and a constitutive model has been built desc...
