In aerospace, motor case design plays an important role as it shields the motor from external factors and also it should withstand high temperature and pressure generated by the motor. This project deals with the design of solid rocket motor casing mainly consists of determi ning the thickness of motor casing which includes the domes at head and cylindrical end welded joints. Modeling of solid rocket motor casing is done in CATIAV5R19. The structural analysis is done for design with different materials like maraging steel,D6AC Steel,austentite and martensitic steels by means of ANSYS 14.5.The design with the best deformation properties of considered materials is considered after comparison and the results are concluded accordingly. Also, comparison is done for Vo n - Mises stresse s , Hoop and Longitudina /Axial stresses for evaluation of both numerical and analytical analysis of the model.
