| Abstract | In ship’s life cycles, corrosion can be an important factor for degradation of structural capacity. According to practical observations, non-uniform corrosion takes place instead of uniform corrosion, while investigations status quo on non-uniform corrosion are not enough and are mainly focused on unstiffened plates. So it is necessary to further study the load capacity of ship structures under non-uniform corrosion. In this paper, the ultimate strength of typical bottom panels in container ships under random non-uniform corrosion is studied by Nonlinear Finite Element Analysis (NFEA), and the load-displacement curves and collapse modes are derived. Additionally, the random nature of non-uniform corrosion is modelled and Monte Carlo Simulations (MCS) are performed to study the probabilistic characteristics of ultimate strengths for corroded structures, and the results are compared with uniform corrosion and pitting corrosion according to our previous research. Influences of boundary conditions are also studied. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
