Futures in Mechanics of Structures and Materials is a collection of peer-reviewed papers presented at the 20th Australasian Conference on the Mechanics of Structures and Materials (ACMSM20, University of Southern Queensland, Toowoomba, Queensland, Australia, 2 – 5 December 2008) by academics, researchers and practicing engineers mainly from Australasia and the Asia-Pacific region. The topics under discussion include: - Composite structures and materials- Computational mechanics- Earthquake and wind engineering- Fire engineering- Geomechanics and foundation engineering- Mechanics of materials- Rehabilitation of structures- Reinforced and prestressed concrete structures- Reliability and sustainability of structures- Shock and impact loading- Steel structures- Structural dynamics- Structural health monitoring- Structural mechanics- Timber engineeringFutures in Mechanics of Structures and Materials will be a valuable reference for academics, researchers and practicing engineers working in structural and material engineering and mechanics.
