... et al. 2015). 2 Methodology The eight years of experience and research on the rock strength in ONKALO and executing the POSE in situ experiment reveal that the rock mass failure is governed by fracture growth on lithological borders. A two-fold failure criterion was proposed (Siren et al. 2015b...

... 1 Introduction A long period of exceptionally high temperatures in Finland in the summer of 2015 was associated with the formation of large ‘exfoliation’ or ‘sheeting’ fractures on Långören Island in the Finnish Archipelago. A video of the event shows sharp fractures forming along the edge...

... 1 Background In geological vocabulary, the term "brittle" is used to describe deformation behaviour in which the rock loses continuity (Van der Pluijm & Marshak 2004), or as the permanent change that occurs in a solid material due to the growth of fractures and/or due to sliding...
