The mechanical behaviour and failure modes of volcanic rocks: a review
MJ Heap, MES Violay - Bulletin of Volcanology, 2021 - Springer
The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …
