| Summary | This course follows on from previous courses on dynamics (Dynamics 3 and Dynamics 4) and aims to provide the students with an advanced understanding on linear and non-linear dynamic systems for a range of applications. Teaching and learning will be focused on the theory of dynamics, wave propogation and target practical and industrial applications. |
| Course description |
Week 1: Introduction to impact mechanics
Terminology, analysis methods and ruling dynamic principles. Low and high energy impact. These topics will be introduced with examples and applications in structural dynamics and structural impact, crashworthiness and vehicle safety, armour and protection systems.
Weeks 2: Collinear impact
One dimensional rigid body impact: equations of motion, compression and restitution and energy balance. Multi-dimensional rigid body impact. Crashworthiness.
Weeks 3-4: Wave propagation
Elastic and plastic waves: wave velocity and propagation, impact of finite length bars. Shock waves: hydrodynamic behaviour of materials, relationships between shock parameters and shock wave profiles. Shock wave interaction, reflection and attenuation. Material response to shock waves.
Week 5: Ballistics
Impact and residual velocites furing impact testing. Ballistic limit of materials. Energy balance. Governing equations. Energy density. Examples and applications.
Week 6-7: Materials testing
Experimental techniques, instrumentation and theoretical methods to obtain constitutive relations in the dynamic regime.
Week 8: Dynamic behaviour of materials
High strain rate behaviour of materials. Constitutive models. Strain rate dependency in metals and composites.
Week 9-10: Penetration mechanical & hybrid shields
Human vulnerability, armour and protection. Early applications and empirical models of penetration. Accidents, threats and targets. Materials for armour and protection systems.

Learning Outcomes
On completion of this course, the student will be able to:
- ¿ Select the appropriate method to analyse the non-linear dynamic response of simple structural elements and apply simplified models to analyse dynamic systems.
- ¿ Select appropriate materials for energy absorption purposes.
- ¿ Propose designs for simple structures and systems for impact protection and energy absorption.
- ¿ Understand wave propagation and interaction, and its effect on the behaviour of solid materials.
