Module Title:Mechanics of Materials 4
Language of Instruction:English
Credits: 5
NFQ Level:8
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: The module will be delivered using lectures and tutorials with a mixture of presentations, example exercises, question and answer sessions, group discussions and online resources. Laboratory classes will be delivered to students working in groups to obtain experimental data with subsequent individual reporting/assessment.
Module Aim: • To provide the student with a specialized knowledge of the internal effects of forces applied to structures, as evidenced by the stresses and deformations produced. • To provide the student with a specialized knowledge of the response of structures due to the properties of materials
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Develop finite element models of simple structures to solve for load, deflection and stress.
LO2 Describe and predict the behaviour of materials in service. Specify and select suitable materials for engineering applications.
LO3 Analyse relationships between stress and strain in mechanical systems
LO4 Predict the behaviour and/or failure of mechanical systems subjected to loads for the purposes of design.
