| DESCRIPTION | This unit introduces the fundamental principles of Solid Mechanics by means of a model body - beam. The theories relating the external loads to the internal load intensity and the elastic strain are developed using the model of an elastic body under the linear boundary conditions. The understanding of these principles is strengthened by their applications to the practical problems. The study-unit will provide the necessary knowledge to: - Mechanical properties of materials, stress v.s. strain curves, direct stresses, average shear stress, factor of safety, stress concentrations; - Tension/Compression 鈥� normal stress, deformation, strain energy; - Torsion 鈥� the elastic torsion of circular cross-sections and closed thin wall sections, shear stress, angle of twist, strain energy; - The simple theory of bending, the property of the cross-section area and its contribution to stress and strain distribution, section modulus, bending of beams with symmetrical and un-symmetrical cross section, bending of initially curved beams, bending stress related to the applied load, strain energy; - Slope and deflection of beams due to bending - relationship between loading, shearing force, bending moment, slope and deflection; - Shear stress distribution in beams 鈥� the relationship between bending moment, shearing force and intensity of loading, vertical shear stresses in beams, horizontal shear stresses, shear centre; - Statically indeterminate and continuous beams; - Combined loads 鈥� the principle of superposition applied to bending stresses, direct stresses and shear stresses, skew or unsymmetrical bending; Complex stress analysis - plane stress and plane strain, principal stresses and principal strains with use of the Mohr鈥檚 circle; - Euler鈥檚 theory of elastic buckling. Study-unit Aims: To introduce the concept of stress and strain induced in the elastic body resulting in different behaviour of the structure and appreciate the effect of the external load on the functionality of the structure. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Evaluate deformation and the load intensity within the structure. - Identify locations where the stress intensity approaches the limit values or the deformation would result in malfunctioning of the structure. 2. Skills: By the end of the study-unit the student will be able to: - Analyze a simple structure under the complex load, formulate appropriate mathematical model of the situation and compute the corresponding stresses, strains, and deformation within the elastic limits. - Evaluate the strength of the structure in relation to the material of the structure. Main Text/s and any supplementary readings: - Mechanics of Engineering Materials, P.P. Benham, R.J. Crawford, C.G. Armstrong. - Mechanics of Materials, R.C. Hibbeler. |
