Course Description:
Rationale and Purpose of the Module: To analyse stresses and strains in a uniaxial stress field and stresses in a bi-axial stress field. To understand how to evaluate stresses in a cylindrical beam subjected to point loads, uniformly distributed loads, couples and torques. As (2) for beams of symmetrical section without torsion. To understand the significance of the connection between the elastic constants. To understand the approach to the analysis of statically indeterminate problems. Syllabus: Uniaxial stress and biaxial strain fields. Constitutive relations. Shear force and bending moment diagrams, Bending of beams, Transverse shear stress in beams, Composite beams, Thermal stress, Torsion of cylindrical sections, Analysis of stress at a point in 2D, Principal stress and Mohr's stress circle, Thin cylinders and thin spherical vessels. Learning Outcomes: Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis) To demonstrate that it is possible to have a stress without a strain, a strain without a stress and a strain of opposite sign to the stress on a plane. To relate the elastic constants to each other. Calculate the second moment of area of various shaped beam cross sections and thus combine shear force and bending moment diagrams to evaluate bending and transverse shear stresses in beams. Given the bending, transverse shear and stresses induced by torsion in a beam be able to determine the principal stresses by calculation and by MohrÆs stress circle. To calculate the stress in a thin walled vessels subjected to internal pressure. To analyse the nature of stress and strain in composite sections subjected to applied forces and temperature variations. Affective (Attitudes and Values) To differentiate between ductile and brittle materials and their mode of fracture Psychomotor (Physical Skills) To perform various mechanical tests to characterise the mechanical response of engineering materials to a variety of loading types
