| GIM5016 | Ship Structure Analysis | 3+0+0 | ECTS:7.5 | | Year / Semester | Spring Semester | | Level of Course | Second Cycle | | Status | Elective | | Department | DEPARTMENT of NAVAL ARCHITECTURE and MARINE ENGINEERING | | Prerequisites and co-requisites | None | | Mode of Delivery | Face to face | | Contact Hours | 14 weeks - 3 hours of lectures per week | | Lecturer | Doç. Dr. Hasan ÖLMEZ | | Co-Lecturer | | | Language of instruction | Turkish | | Professional practise ( internship ) | None | | | | The aim of the course: | | 1. Assumptions the design loads on the ships for strength calculation methods used.
2. To encourage the students to use library and other resources (internet etc.) and to make medium scale research on given problems
3. Modeling of local ship structures using matrix displacement method.
4. Applications with FEM.
5. Understanding of plate buckling, bending, stiffned panels,etc. such as advanced strength concepts. |
| Programme Outcomes | CTPO | TOA | | Upon successful completion of the course, the students will be able to : | | | | PO - 1 : | Familiarize the strength based calculations in naval architecture. | 1,2 | 1,3,5 | | PO - 2 : | Familiarize the strength problems of ship structures. | 1,2 | 1,3,5 | | PO - 3 : | ship structure of the plane frames, continuous beams and so on. Using the matrix displacement method to our model, such as local structural modeling will be learned. | 1,2 | 1,3,5 | | PO - 4 : | Gain the ability of solving the structural problems of ships. | 1,2 | 1,3,5 | | CTPO : Contribution to programme outcomes, TOA :Type of assessment (1: written exam, 2: Oral exam, 3: Homework assignment, 4: Laboratory exercise/exam, 5: Seminar / presentation, 6: Term paper), PO : Learning Outcome | | |
