On the Design of Composite Patch Repair for Strengthening of Marine Plates Subjected to Compressive Loads

Marine structures are susceptible to corrosion that accelerates material wastage. This phenomenon could lead thickness reduction the extent in which local buckling instabilities may occur. The majority of existing repair techniques require welding, is a restricting factor flammable environments where hot work prohibited. A novel methodology has attracted research focus for over two decades adhesive bonding composite patch on ship’s damaged plating. Although most studies have been focused against crack propagation, restoring initial strength corroded marine plates high interest. In this work, technique assessed using numerical experimentation through finite element analysis (FEA) with patch’s dimensions as design parameters. results then evaluated design-of-experiments (DOE) approach by generating response surface from central (CCD) points. Applying various and patches makes it possible create procedure specifies minimum requirements depending metal substrate’s realized.
