Subject Description

Unit 1, Stress Analysis: On completion of this subject students should understand the principles of energy methods as applied to solving a variety of problems in elasticity, including statically indeterminate ones. Comprehend the nature of inelastic deformation and its basic governing laws together with their application to simple manufacturing processes. Understand the techniques of experimental stress analysis. Topics covered include: energy methods in stress analysis, stationary potential and complementary energy theorems, virtual work, Castigliano's first and second theorems, method of Rayleigh-Ritz, statically indeterminate systems, suddenly applied loads, impact stresses, inelastic behaviour, yield criteria, constitutive relations, work hardening, testing methods, basic problems in inelastic deformation, structural modelling and analysis, introduction to the finite element method, experimental stress analysis, fracture mechanics and fatigue.

Unit 2, Mechanics of Rigid Bodies: On completion of this subject students should be able to understand the principles of three-dimensional mechanics of rigid body and carry out kinematic analysis of mechanical systems. Topics covered include: motion of particles in terms of inertial frames, motion of particles in terms of translating and rotating frames, matrix of directional cosines, Euler's angles, angular velocity and angular acceleration, Coriolis statement, motion of a rigid body, kinetics of a system of particles, linear and angular momentum, inertia constants, parallel axes theorem, principal axes, Euler equations, modified Euler equations.

Assessment

Laboratory/tutorial work, assignments and tests up to 30 pages equivalent. One examination not exceeding three hours. Students will be notified of the weighting of assessment components at the beginning of semester.
