# STRUCTURAL MECHANICS & FINITE ELEMENTS - 2019/0

Module code: ENGM053

## Module Overview

The Finite Element Method (FEM) is the most commonly used tool in practice for structural design and analysis of bridges, buildings and other types of structures. In order to carry out a successful FE analysis, a basic knowledge of the theory behind the FEM is required as well as an understanding of the applications to different types of structural elements & analyses. This module covers both of these two aspects which are essential for learning how to perform a FE analysis.

## Prerequisites / Co-requisites

Knowledge of structural mechanics to FHEQ Level 6

## Module content

• Stiffness method, numerical tools used in the finite element method (interpolation, shape functions, numerical integration, co-ordinate transformation), virtual work, FEM matrix framework

• Finite element families (iso-parametric elements, non-conforming elements) & their tests: truss & frame elements, plates & shell elements, plane stress elements, solid 3D brick elements

• General considerations in FE modelling: loading, boundary conditions, symmetry, model connections, linear elastic analysis, introduction to non-linear static analysis (geometry and material non-linearities), introduction to dynamic FE analysis and extreme loading.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate knowledge and understanding of theory and fundamentals behind the finite element method and its applications in design and analysis of Structures (LO 1) through a 2 hour unseen examination. LO’s 2 and 3 are assessed through the design/analysis coursework.

Thus, the summative assessment for this module consists of:

• Unseen written examination (75%), 2 hours – [LO assessed 1]

• Coursework assignment 1 (10%) – [LOs assessed 2,3,4,5]; estimated working hours 15; 15 page report on using Stiffness method and FE of trusses.

• Coursework assignment 2 (15%) – [LOs assessed 2 ,3,4,5]; estimated working hours 22, 15 page report on plane stress or shell element modelling and FE.

Formative assessment and feedback are through a range of self-assessment exercises (named “home exercises”). The final solution to these exercises is given so that students can check their answers. Worked examples are also given. Feedback is also given on SurreyLearn in forum discussions and through comments on coursework submissions.

## Module aims

• provide an appreciation of the theory behind the finite element method and the applications of this method in the design and analysis of Structures.
• provide the ability to use commercial finite element program to model structures using different types of elements.
• provide an overview of the different types of finite element analysis and levels of complexity generally used in practice to obtain a specific desired level of accuracy and achieve economic and safe structural designs.

## Methods of Teaching / Learning

30 hrs lectures, 10 hrs tutorials/question classes/self- assessment questions, 2 hrs video tutorials, 37 hrs assignment work, 71 hrs independent learning. Total student learning time 150 hrs.

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.
