Following the success of the First International Conference on Rock Dynamics and Applications (RocDyn-1) in Lausanne Switzerland in June 2013, the Second International Conference on Rock Dynamics and Applications (RocDyn-2) will be held in Suzhou China in May 2016. RocDyn-2 will be organised by the Institute of Rock and Soil Mechanics of Chinese Academy of Sciences, together with 4 other universities around the World. Rock dynamics covers a huge scope of research to understand the dynamic behaviour of rock materials, rock joints and rock masses, including the initiation and the propagation of stress waves, the responses and the failures of rocks under the dynamic and static loads. It has wide applications in civil, mining, hydropower, petroleum engineering, including the new rock engineering applications such as shale gas, hot rock geothermal energy, and earthquake hazard management. With extensive research conducted worldwide and increasing engineering projects applying rock dynamics, RocDyn-2 is organised to address scientific research as well as engineering applications. RocDyn-2 organisers would like to welcome scientists, engineers and students involving in rock dynamic research and engineering practice to join us in Suzhou, to share our knowledge, to cooperate on researches, to advance rock dynamics and engineering applications.
