Educational Aims
To enable students to 1] understand and apply fundamental engineering mechanics concepts, theories and methodologies, in order to carry out stress and deformation analysis of engineering components for the purpose of producing efficient designs. To gain an understanding of basic numerical and experimental methods, and a general understanding of the applicability of various analytical, numerical and experimental techniques to specific applications; and 2] apply engineering mechanics concepts and materials behaviour models to predict the failure loads and/or lives of engineering components in order to carry out efficient designs/assessment. To gain an understanding of the various types of materials constitutive models available, their origins and their use in describing and predicting failure loads and modes of failure in engineering components.Learning Outcomes
