This course is designed for students of Mechanical Engineering to enhance their knowledge and proficiency in the design analysis of “Structural materials” such as beams, columns and shafts. This course meets the needs of students in machine design and assists the students to determine the behaviour/response of materials to bending moments, shearing stresses and strains. Students will learn the principle of beam deformation under static and dynamic loads and the relationship between the radius of curvature, bending moments, bending stresses and material’s cross-sectional dimensions is established. Students will also learn the principle of ‘Beam Deflection’ and establish the relationship between slope, deflection and radius of curvature for beams under various loading conditions. Methods of determining beam slope and deflection: Double integration method, Moment area method, Macaulay’s method, etc will be taught. Further topics to be covered include: unsymmetrical bending and shear centre, application of strain energy, biaxial and triaxial state of tresses, Mohr’s cycle, normal stress, stress components; failure theories, creep, fatigue, fracture and stress concentration, factor of safety, thin walled section and concept of bimoment, development of slope deflection equations and matrix structural analysis programs. The students will finally be divided into groups and be made to develop slope, bending and deflection equations for solid and thin walled beams and to carryout matrix structural analysis programs on them. They are required to give group presentations which would be graded.
