BIOMECHANICS - 2022/3

Module code: ENG2097

Module Overview

This is an introductory level course in biomechanics. Topics taught in modules on solid and fluid mechanics are reviewed  and then used to analyse certain aspects of the functioning of the human body.  The topics covered are:


  • Biomechanics of movement and analysis of the musculoskeletal system.

  • An introduction to the material behaviour of biological tissues.

  • An introduction to the fluid mechanics of the cardiovascular system.

Assessment Strategy

The assessment strategy is designed to: provide students with the opportunity to demonstrate that they have developed a good understanding of how the fundamental principles of mechanics can be applied to analyse the human body.

The continual assessment portion is divided into two parts. In the first part, the students are required to independently solve quantitative problems similar to those covered in tutorials. Apart from assessing their grasp of the taught material during the course of the module delivery, this part of the assessment provides an opportunity for formative feedback. In the second part, the students are provided with the opportunity to go through all the stages of the process of analysing human movement experimental data, thus linking together a number of concepts and skills acquired in lectures and tutorials in a logical sequence. The students are encouraged to write a computer program (e.g. in Matlab) to perform this analysis. Formative assessment and feedback is provided in form of weekly quizzes and additional quantitative sets of problems based around processing and analysis of real-life data.

The examination covers all topics delivered in the lectures and it is aimed at assessing both the understanding of theoretical concepts and the ability to apply these in practice.

Thus, the summative assessment for this module consists of:


  • Examination              [ Learning outcomes 1, 2,3,4,5,6 ]    (2 hours)                 {75%}

  • Coursework :  quantitative analysis of experimental motion-tracking data [ Learning outcomes 1,2,3, 5]  (12 hours) {25%}



Formative assessment and feedback


  • Weekly quizzes and sets of formative quantitative assignments

  • Formative verbal feedback is given in tutorials.

  • Written feedback is given for each of the coursework reports.



 

Module aims

  • An understanding of how the human body can be represented as a mechanical system at various levels of detail depending on the application, and then analysed using principles of mechanics.
  • An understanding of the way in which muscles and joints act as structures to provide equilibrium or generate movement.
  • An understanding of how the principles of statics and dynamics can be applied to calculate forces generated in the joints for a range of situations.
  • An understanding of the techniques that humans use in locomotion to move with a minimum of energy expenditure.
  • An in-depth understanding of all the steps involved in the analysis of human movement and the practical skills needed to conduct that analysis.
  • An understanding of how stress analysis can be applied to the long bones to examine their functional behaviour, fracture modes, and resilience.
  • An introduction to the material behaviour of soft tissue.
  • An introduction to the analysis of the cardiovascular system from the perspective of fluid dynamics

Methods of Teaching / Learning

The learning and teaching strategy is designed to give the student an introduction to the field of biomechanics with a combination of lectures, tutorial sessions, and guided learning via formative assessment.  

The purpose of lectures is to familiarise students with fundamental concepts in biomechanics and to enable them to acquire knowledge on selected topics in this field. Furthermore, the students are motivated to synthesize knowledge gained across other engineering modules for the purpose of analysing problems in biomechanics. Lectures are delivered in person. Video recordings of all lectures are available to the students via the SurreyLearn VLE.

Tutorials are used to reinforce the newly acquired knowledge and to further develop understanding through solving quantitative problems. Problem solving skills and techniques are given special attention.

Formative assignments are provided in form of weekly quizzes and quantitate sets of problems. Quizzes are used to test and reinforce the understanding  of core concepts introduced in the material delivered in that week. Quantitative problems are based around processing and analysing real-life experimental data. They provide students with the opportunity to link the theory with application.

The learning and teaching methods include:


  • 2 hours face-to-face lecture per week x 11 weeks

  • 1 hour face-to-face tutorial per week   x 11 weeks

  • Formative assessment x10 weeks


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.
