 Level of Course Unit  Second Cycle  Objectives of the Course  The main objective of this course is to introduce the student to the analysis of linear elastic solids once subjected mechanical and thermal loads. The primary intention is to provide for students the essential fundamental knowledge of the theory of elasticity together with a compilation of solutions of special problems that are important in engineering practice and design. In addition to that, the topics carried out in this course will provide a foundation for other solid mechanics courses such as theory of plates and shells, elastic stability, composite structures and fracture mechanics and constitutive elasticplastic models.  Name of Lecturer(s)  Yrd. Doç.
