A protective wall for use in a structure such as a ship comprises a first and second metal layer, with an armor plate in between and layers of elastomeric material between the armor plate and the first and second metal layer respectively. The first and second metal layer having a higher ductility than the armor plate, the armor plate being mounted between the first and second metal layer in a way that allows the first and second metal layers to stretch relative to armor steel plate at least in response to forces resulting from impact by fragments from an explosion. When an explosion occurs in a space bounded by the protective wall, the first and second metal layer deflect under the pressure pulses due to blasts, stretching relative to the armor plate. The armor plate blocks high speed fragments. The elastomeric material has a double function: it increases the resistance of the armor plate to fragments and it allows for separation of the armor plate from the first and second metal layer, allowing them to stretch.
A protective wall for use in a structure such as a ship, the protective wall comprising
A protective wall according to any one of the preceding claims, wherein at least one of first and second metal layer are made of titanium or aluminum.
A protective wall according to any one of the preceding claims, wherein the armor plate has a yield stress and tensile strength corresponding to ARMOX 500 or ARMOX 600.
A protective wall according to any one of the preceding claims, wherein the first and second metal layer each have a tensile strength of less than 600 MPa and the armor plate has a tensile strength of more than 1000 MPa.
A method of assembling a structure, comprising attaching a first metal layer to a connection piece, mounting an armor plate coated on both sides with elastomeric material between on the first metal layer attached to the connection piece, attaching a second metal layer to the connection piece and/or the first metal layer and over the armor plate, the first and second metal layer having a higher ductility than the armor plate.
A method of assembling a structure, comprising assembling at least part of the structure with a wall comprising a first and second metal layer attached to elements of the structure, and inserting an armor plate coated on both sides with elastomeric material between the first and second metal layer, the first and second metal layer having a higher ductility than the armor plate.
