SESG6039 Composites Engineering Design and Mechanics

Module Overview

This module provides an in depth coverage of the mechanics of fibre-reinforced polymer materials and structures. The core of the course encompass modelling of the 2D orthotropic lamina reduced from 3D continuum mechanics for anisotropic solids, classical laminate theory and the assumption of orthotropic material behaviour, structural modelling of composite beams and plates, and consideration of damage and prediction of failure. The students will gain an understanding of the deformation and failure behaviour of composite materials and structures through application to specific design applications in project work. The concepts of damage and failure will be introduced along with details of assessing material behaviour through mechanical testing and microscopic evaluations. A laboratory class will introduce the effects of manufacturing processes and material construction. Assignments based on the laboratory will enable student to analyse and predict the behaviour of specific materials configurations using a rational mechanics based approach.

Aims and Objectives

Module Aims

• To give students a thorough grounding in the theory, properties and manufacturing of modern composite materials. • To enable students to develop structural designs using composite materials. • To provide the students with a background in composite materials which serves as a basis/preparation for working in the composites engineering industrial field.

Assessment

Assessment Strategy

Referral method - Normally the referral for this module consists of resubmission of the coursework/s on laboratory work and individual assignments, with the mark on Coursework Group project unchanged from the first attempt. In case the mark for the Coursework Group project is below the qualifying mark and alternative referralassignment will be provided. External repeat of this module is only possible if the Coursework Group project has been passed at the qualifying mark.
