DR. Ömer Necati CORA, | | Language of instruction | | | Professional practise ( internship ) | None | | | | The aim of the course: | | To provide the student with the basic concepts of internal forces created by external loads in a deformable body and their effects on the body (stress and deformation) and to develop the student's ability to use/apply these concepts in analyzing engineering design problems. |
| Learning Outcomes | CTPO | TOA | | Upon successful completion of the course, the students will be able to : | | | | LO - 1 : | determine the stresses in the elements subjected to combined loadings. | 1,2 | 1, | | LO - 2 : | learn how to tranform the stress and strain components form one plane to another. | 1,2 | 1 | | LO - 3 : | obtain the stresses in the thin-walled pressure vessels. | 1,2 | 1 | | LO - 4 : | predict the failure of a material subjected to a multiaxial state of stress. | 1,2 | 1 | | LO - 5 : | decide how to design a shaft and a prismatic beam subjected to both bending and shear loadings. | 1,2 | 1 | | LO - 6 : | obtain the strain energy of a member subjected to external loading | 1,2 | 1 | | LO - 7 : | analyze the static and hyperstatic systems by using energy methods. | 1,2 | 1 | | LO - 8 : | obtain the stresses in the columns subjected to axial compressive load. | 1,2 | 1 | | 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), LO : Learning Outcome | | |
