Before his tragic accident, Ioannis Vardoulakis was working on his new book on Cosserat Continuum Mechanics. The draft was almost ready. With the help of his family, Eleni Gerolymatou, Ioannis Stefanou, Manolis Veveakis and myself have prepared the manuscript for publication.
I am glad to let you know that it has just been published by Springer in Lecture Notes in Applied and Computational Mechanics series (https://www.springer.com/us/book/9783319951553). I am sure that this new book will be of great interest for the ALERT community and more generally for researchers and scholars interested in multiscale modelling as it provides the fundamental tools of Cosserat theory with examples and applications to the mechanics of granular media.
