| Summary | This course follows from previous courses on dynamics (D3 and D4). It aims to provide the students with an advanced understanding on analytical and experimental structural dynamics systems, and impulse dynamics of non-linear systems. The course covers aspects on structural dynamics for modal analysis and applications (Module I) and wave propagation theory (Module II). Teaching/learning will be focused on analysing dynamical system in time and frequency domain, as well as impact response of structural materials, including ballistic and shock regimes. Engineering applications in civil, automotive, aerospace and defence will be explored.

Module II: Impulse dynamics and impact response of structural materials (12 hours)
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.
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.
Dynamic testing and ballistics
High strain rate behaviour of materials. Dynamic testing. Ballistic limit of materials. Energy balance. Governing equations. Energy density. Examples and applications.
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.
