MATERIALS & STATICS - 2022/3

Module code: ENG1063

Module Overview

The Materials element of this module provides an introduction to a range of common material properties and outlines major classes of materials. The Statics part of the module aims to introduce students to the basic principles of statics and provide an introduction to elementary strength of materials (direct and bending stresses).

Assessment Strategy

The assessment strategy is designed as follows:

For materials, to provide students with the opportunity to demonstrate understanding of the most important mechanical properties of the various main classes of engineering materials and related factors of materials selection, durability and aspects of processing.

For statics, to provide students with the opportunity to demonstrate the ability to apply the principles of structural mechanics to the analysis of 1D and 2D problems.

Summative assessment


  • Examination    [Learning outcomes 1,2,3,4]

  • Coursework     [Learning outcomes 1,2,3,4]



Formative assessment and feedback

Materials:  Formative verbal feedback is provided through tutorials (5 hours) where students are provided with individual comments on how they have approached solving problems; students are also provided with written solutions which provide a thorough exposition of the correct solution to the problems and also an indication of the various steps in the solution where it may have been possible to go astray and hence produce an incorrect answer.

Statics: Formative assessment and feedback is provided via the weekly supported tutorial work  (10 hours) and through self-assessment exercises provided via SurreyLearn.  The students complete a set of worked solutions to a range of questions in the tutorial classes and are provided with tutor support in comment and feedback in the sessions.  

Module aims

  • To define and discuss the main mechanical properties and durability of engineering materials and to review the salient features of the main classes of materials in the context of these properties. In addition, factors relating to materials selection and design, processing and sustainability will be addressed.
  • To provide students with an introduction to the fundamental concepts of engineering analysis, as applied to the strength and stiffness of statically determinate structures with uniaxial stress fields.

Methods of Teaching / Learning

The learning and teaching strategy:

The module introduces the fundamentals of Engineering Materials for the MEng and BEng programmes in Mechanical, Aerospace, Medical, Automotive and Civil Engineering, including a wide variety of applications.  In addition, the module introduces the basis for structural mechanics leading to topics in Solid Mechanics (ENG1066 and ENG1076) and Structural Engineering at FHEQ Level 5, 6 and 7 on the MEng and BEng programmes in Mechanical, Aerospace, Medical, Automotive and Civil Engineering. 

The learning and teaching methods:

Materials:


  • 2 hours captured contents x 11 weeks

  • 1 hour live lectures x 11 weeks

  • 1 hour tutorial (in groups) in weeks 2, 4, 6, 8, 10



Statics:


  • 1 hours captured contents x 11 weeks

  • 1 hour live lectures in weeks 1, 3, 5, 7, 9, 11

  • 1 hour tutorial (in groups) in weeks 1, 3, 5, 7, 9, 11



Revision:


  • 2 hours captured revision contents


Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
