The objective of this short course over four days is to acquaint professional engineers, researchers, students and others to procedures and concepts for the analysis and design of structural elements subjected to large dynamic loads produced by explosions and impact. The course examines aspects of the various types of dynamic loads, studies the important relevant material characteristics in the dynamic range and, in particular, explores the response and energy absorbing properties of various structural systems, including damage and failure. Reference to the manual UFC 3-340-0211 that presents design methods for protective construction, and some ‘hands-on’ sessions will be included. Participants will be given spreadsheet programs to practice some of the examples presented, as well as the latest edition of the book Structural Impact2. The course is designed to be of use to anyone interested in the structural impact fields, structural crashworthiness, explosion mitigation, hazard assessment and safety calculations throughout the civil, mechanical, nuclear, transportation, petrochemical and process industries. It is particularly suitable as a primer on impact and blast effects.

Over a period of four days, lectures will be presented on the following topics:
- Introduction and general considerations
- Quasi-static approximation
- Elementary impact and stress wave considerations
- Energy-absorbing systems
- Human impact injury criteria
- Structural crashworthiness
- Blast effects and design requirements
- Loading on structures caused by external air blast
- Pressure-impulse diagrams and their applications
- Dynamic response and single-degree-of-freedom (SDOF) analysis methods
- Analysis and design of ductile elements under blast loading
- Examples using spreadsheet analysis tools
- Dynamic properties of ductile materials
- Failure, perforation and post-severance response of structures
- Energy-absorbing and sacrificial-cladding systems
- Sandwich structures
- Dynamic buckling of structures
- Scaling and experimentation
- Two-degree-of-freedom analysis methods
- Analysis and design of non-ductile elements under blast loading
- Introduction to MDOF methods
- Internal loading of structures
- Damage-vulnerability relationship
The ‘hands-on’ sessions require the use of a Windows compatible laptop computer. It is advisable to bring one with you, if at all possible, preferably with Microsoft Excel 2007 (or above) installed.
The Course will start at 9.15 am on Monday, 13 November 2017 and finish at 5.00 pm on Thursday, 16 November.
The course fee includes all working materials, lunch, coffee, tea and all computer facilities used, where applicable. During the course there will be practical sessions for which software will be provided and therefore participants may wish to bring their own laptops. Each participant will receive the course book ‘Structural Impact’ by Prof Norman Jones, free of charge.
Professor Norman Jones FREng FNAE FIMechE FASME FRINA, recently retired as AA Griffith Professor of Mechanical Engineering and Director of the Impact Research Centre at the University of Liverpool, has conducted theoretical, numerical and experimental studies at MIT in the US and the UK over the past 40 years or so into the dynamic behaviour of structures and systems. These studies have clarified the influence of dynamic material properties, dynamic crushing, transverse shear forces, finite deflection effects, failure criteria including perforation, rotatory inertia and other phenomena on the response of a wide range of structural members (beams, plates, shells, pipelines, etc) subjected to impulsive, dynamic pressure and impact loads causing large inelastic deformations.
Professor Jones is Honorary Editor-in-Chief of the International Journal of Impact Engineering, Associate Editor of the Latin American Journal of Solids and Structures, and is on the editorial boards of several other international journals.
He wrote the book ‘Structural Impact’ and has co-edited nine other books, as well as publishing over 300 journal articles. He has won two prizes from the Institution of Mechanical Engineers, another from the Royal Institution of Naval Architects, an Eminent Scientist Award from the Wessex Institute of Technology, and has been invited to serve on many international conference committees as well as delivering plenary and opening addresses. He has honorary professorships at the Huazhong and Taiyuan Universities of Science and Technology in China and was elected to the Royal Academy of Engineering in 1998 and as a Foreign Fellow of the Indian National Academy of Engineering in 2005.
Dr Graham Schleyer FIMechE, is a Senior Lecturer in the Department of Engineering and a member of the Impact Research Centre at the University of Liverpool, having worked previously for several years in the gas industry and for shorter periods with leading research and technology companies in the UK and the US. Over the past 25 years or so he has conducted hundreds of field and laboratory tests on full-size and reduced-scale structures involving gas, HE and pressurized air explosions which has provided useful insights into the explosion resistance of safety critical components and structural systems. An overall advance has been the development of sub-scale experimental procedures which have resulted in the validation of numerical models and approximate design methods for steel, glass and RC structural elements subjected to pulse pressure loads.
Dr Schleyer is a member of the International Scientific Advisory Committee of the International Conference ‘Structures Under Shock and Impact’ organised by the Wessex Institute of Technology. He also serves on the editorial board of the International Journal ‘Computational Methods and Experimental Measurements.’ He is a previous Royal Academy of Engineering Global Research Award holder (formerly Engineering Foresight Awards), and has published widely in journals, conference proceedings, and government and industry reports.

The New Forest is one of the UK's most popular tourist destinations and offers many attractions all year round, including picturesque forest villages as well as beautiful scenery. It is located in Southern England, spreading over 150 square miles of Hampshire. The New Forest was established as a royal hunting ground by King William I, and by the 14th century the land was being used to produce timber for the ship building industry on the south coast. Today, after nearly 1000 years, the forest is still Crown property and is administered by the Forestry Commission. Since the reign of King William I commoners have been given the right to graze their livestock, normally ponies, cattle and pigs, on Forest land where they wander freely. In the New Forest the well-being of the animals and the special needs of the countryside are a priority. The Forest is unarguably recognised as one of the most unique and important wilderness areas in Western Europe and, because of this, it is now a National Park.
Venue and Accommodation
The course will take place at the Wessex Institute of Technology at Ashurst Lodge located in the New Forest, an outstanding National Park that borders the South Coast. Ashurst Lodge is an ideal venue for conferences, courses and seminars. The participants can benefit from an excellent standard of accommodation, either on Campus or in various hotels or bed and breakfasts in the area. The surroundings are equally appealing to those who enjoy walking, horse riding, cycling, sailing and fine landscapes.
For more information on how to find Ashurst Lodge and to arrange accommodation during the courses please use the information provided on the Contact Us page.
During the course a dinner will be held at a venue in the New Forest.
