Rock mechanics – intact rock, rock joints, rock mass
Large and complex infrastructure projects, mines, and storage facilities, energy systems and increased utilisation of the rock material are challenges in the rock engineering area. New and detailed knowledge in rock mechanics, modelling and properties of different rock materials are required to meet these challenges.
Research and commissions
Rock materials and rock masses have complex mechanical behaviors due to their texture and composition that affect deformation and fracture properties. RISE carries out various types of national and international projects to society and companies to provide knowledge about rock materials and how they behave under different load situations. Our high level of quality has been appreciated and has been a requirement in many of the projects specifically aimed at the geological storage of nuclear fuel. Examples of research are in fracture mechanics, fracture processes and mechanics of rock fractures.
Experimental mechanics
Experimental mechanics is one of the cornerstones of the field of rock mechanics, where the development of new and improvement of old test and measurement methods is done to increase knowledge of the properties of rock matter and improve the quality of the results from the experiments. This has been possible as there is a solid knowledge in mechanics and well-equipped laboratories with different types of measurement techniques. A development towards hydromechanics has also been made.
Link between mechanical properties and microstructure
The microstructure of rock materials controls its mechanical properties. For many years, RISE has successfully worked to combine mechanics, geology and petrography to understand the interaction that takes place at different size scales. This knowledge is important to obtain results in order to build advanced models of rock materials or a rock mass.
National and international collaboration and excellence
RISE is active in several national and international industry organisations to keep in touch with the latest developments in the field of rock mechanics. The results of the projects are published in international conferences and in scientific journals in the field when permitted, which gives a quality stamp. Several of our experts are regular reviewers for conferences and scientific journals in the field.
