Failure of the bolt in the aircraft wing is taken for granted in the project, and the consequent repairs are presently very costly. The SMART material investigated in this work is the TRIP steel, and any reference to SMART material, in this work, shall at all time mean TRIP steel. Investigation of the stresses pertaining to bolts in general is carried out, based on the bolt theories and using the finite element analysis. An optimal bolt based on impact resistance only has also been suggested. Metallurgical behaviour of materials similar to TRIP materials is also investigated, including a section dedicated only to TRIP steels. Therefore, the work contained herein acts as a good base for further research.enSteel--Analysis.Bolts and nuts--Fatigue.Bolts and nuts--Defects.Austenitic steel.Martensitic transformations.Martensite.Smart materials.Theses--Mechanical engineering.Thesis
