This module will provide students with extended understanding of the theories in Solids Mechanics and their applicability in stress/strain analysis, including motion/equilibrium equations, compatibility equations, Hooke's law, elasticity and plasticity, boundary conditions for complex engineering problems, and energy methods for stress and deformation analysis. Such essential engineering knowledge will equip students with commonly required capabilities in mechanics modelling, solving a mechanics model for stress and deformation on a practical problem, conducting stress concentration analysis, interpolating experimental data and associating with industrial problems, and performing basic finite element analysis on structure behaviours. Students are expected to comprehensively use the knowledge and skills attained above to solve various real-life engineering problems in their senior- year modules, individual and group projects, and future career.

This module aims to illustrate the fundamental principles of stress and deformation in a solid under complex loading associated with the elemental structures/components in civil and mechanical engineering. The understanding of solids mechanics will provide the ability to analyse problems in terms of strength and deformation in relation to the design, manufacturing and maintenance of machines, vehicles, structures, and devices in the above-mentioned engineering areas.
