SE 110B: SOLID MECHANICS II 1. Catalog Description Advanced concepts in the mechanics of deformable bodies. Unsymmetric bending of symmetrical and unsymmetrical sections. Bending of curved beams. Shear center and torsional analysis of open and closed sections. Stability analysis of columns, lateral buckling. Application of the theory of elasticity in rectangular coordinates. 2. Prerequisites SE 110A 3. Textbook and Other Required Material Craig, R.R., Jr., Mechanics of Materials, 2nd edition, John Wiley & Sons, 2000. (MD Solids v.1.7 software included with textbook). 4. Course Outcomes Letters in parentheses relate to the course outcomes a. To provide a fundamental understanding of the response of deformable bodies to applied loads in non-elementary cases (a, b, c). b. To further the understanding of the mechanisms by which a structure sustains loads safely (d, f, h, j). 5. Topics Covered a. Three-dimensional stress/strain with Mohr's representation b. Failure criteria c. Stress concentration d. Deflection of beams e. Energy methods f. Torsion of open and closed sections g. Unsymmetric bending and shear center in beams h. Buckling of columns 6. Class/Laboratory Schedule A total of 4 hours of classroom instruction per week will be required. 7. Method of Assessment and Evaluation · Bi-weekly homework assignments consisting of solving solid mechanics problems of increasing complexity (10%). · Mid-term exam including questions related to 3D stress/strain, beam deflection, energy methods and torsion of open and closed sections (40%).


Final exam covering the entire course material while emphasizing unsymmetric bending, shear center in beams, and buckling of columns (50%).

8. Relationship of Course to Program Objectives Letters in parentheses relate to the program educational outcomes. The course is structured to further the understanding of the analysis of deformable solids subject to applied loads. It builds on aspects covered in SE 110A Solid Mechanics-I while examining problems that are complex in terms of either the geometry of the solid (open sections, curved beams) or the configuration of the applied load (unsymmetric bending, lateral buckling). The course content enables the development of the students' ability to apply principles of mathematics and physics to the study of complex deformable bodies subject to external loads (a, c). The structure of the course requires students to solve engineering problems that apply to real world structures and structural components (c, e, h). The assignments build skills in written communication (g). Development of verbal communication skills is provided by frequent engagements in class discussions that are strongly solicited by the instructor (g). The aspects of professional responsibility are emphasized through discussions, exercises and case studies relating to real world applications (f). 9. Contribution of Course to Meeting the Professional Component The course provides the basis for the analysis of structural components and structural assemblies under loads in non-elementary cases. It fits well with the broad nature of structural engineering as the concepts studied apply equally to aerospace, civil, mechanical and naval/offshore engineering. 10.
