# SOLID MECHANICS 1 - 2022/3

Module code: ENG1066

## Module Overview

This module consists of two components: stress analysis and dynamics. Stress analysis extends the work in stress analysis from uni-axial to multi-axial conditions;  Dynamics is the study of the motion of objects under applied forces and the mathematical modelling of physical phenomena.

## Module content

Indicative content includes:

Stress analysis

Multiaxial behaviour: stress transformation of two-dimensional stress states; principal stresses; strain and strain gauges; strain transformation and principal strains; multi-axial stress-strain relationship; Poisson's ratio and generalized Hooke's law, and the relationship between G, E and n; introduction to failure criteria according to Rankine, Tresca and von Mises.

Stress analysis in mechanical design: uniform torsion, non-uniform torsion and statically indeterminate problems featuring torsion; transmission of power by circular shafts; combined bending and torsion of shafts

Dynamics

Principles of displacement, velocity and acceleration; coordinate systems, vectors and vector notation; relative motion; free-body diagrams; conservation of linear momentum, collisions, internal and external forces, impulse and constrained motion; angular momentum of particles; conservation of momentum of rigid bodies, external moments, moments of inertia and constrained motion.

## Assessment pattern

Assessment type Unit of assessment Weighting
Coursework STRESS ANALYSIS COURSEWORK 10
Examination FINAL EXAMINATION (2 HOURS) 90

## Alternative Assessment

There is no alternative assessment.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate that they have developed a good understanding of the fundamental principles and physics underlying the behaviour of objects with applied loads, as well as their motion in response to those loads. The summative stress analysis coursework allows students to demonstrate the development of their practical problem-solving skills.

Thus, the summative assessment for this module consists of:

• Stress analysis coursework [Learning outcomes 1, 2]

• Examination [Learning outcomes 1, 2, 3, 4, 5]

Formative assessment and feedback

• Formative verbal feedback is given in all tutorials

• A formative dynamics test is available on SurreyLearn to provide feedback on understanding of principles and problem-solving approaches

## Module aims

• The elastic responses of solid components to externally applied loads including multi-axial stresses and strains, stress-strain relationship, failure criteria
• The motion of systems of particles and rigid bodies with and without mass and/or external forces

## Learning outcomes

P - Professional/Practical skills

## Methods of Teaching / Learning

The learning and teaching strategy is designed to introduce students to the fundamental concepts in statics, stress analysis, dynamics and their applications through the development of the theoretical framework and its application to practical problem-solving.

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.
