Seminar overview:

Combining x-ray tomography and 3D image analysis has finally opened the way for experimental micro-(geo)mechanics, allowing access to different scales of interest. In this talk a few examples will be presented of the kind of experimental results that can be obtained by means of x-ray micro tomography imaging. Images from x-rays can be analyzed either in a continuum sense (using 3D Digital Image Correlation) or looking at the individual particle kinematics. These advanced techniques offer us a look at what actually happens when a granular material deforms and eventually fails. However, there are issues when the scale of interest is very small, for example the characterization of grain-to-grain contacts (their orientations and evolution), or production of fines by grain breakage. These challenges will also be discussed through a few examples.

Biography:

Cino Viggiani was born in Napoli (Italy) and obtained a Ph.D. in Geotechnical Engineering at the University of Roma “La Sapienza” in 1994. He is a Professor of Solid Mechanics and Civil Engineering at the Université Grenoble Alpes in France since 2004. He served in the capacity of Vice-President for Research in Physics and Engineering from 2007 to 2011, and he is the Head of Laboratoire 3SR in Grenoble since 2013. His research involves experimental investigations as well
as theoretical and numerical modelling of the behaviour of geomaterials, including localized failure and hydro-mechanical coupling. Applications are principally in geoenvironmental, petroleum, and civil engineering. On the experimental side, he has been developing and using quite a range of soils and rock testing apparatus, as well as advanced methods such as x-ray tomography and Digital Image Correlation.

"Designing and Constructing the Exhibition Road Quarter at the V&A" by Dr Stuart Hardy (Arup)

Seminar overview:
As part of the ongoing 'FuturePlan' estates redevelopment at the Victoria and Albert Museum (V&A) in South Kensington, the Trustees of the V&A commissioned a new world class gallery in the Boiler House Courtyard adjacent to Exhibition Road. The gallery is constructed entirely below ground to create a new public courtyard and feature entrance above, with virtually no superstructure to hold the basement down. Stuart will discuss some of the novel design solution used, the ground breaking research that has been incorporated into the fabric of the basement and challenges encountered during construction.

Short biography:

Stuart is an Associate Director in the London geotechnics group of Ove Arup & Partners Ltd. After completing an undergraduate degree in Civil Engineering and a PhD in geotechnical engineering at Imperial College, Stuart has worked on a number of challenging basement and foundation projects located mainly in the Middle East and London. These have included the new Wembley Stadium, the Exhibition Road Building for the Victoria and Albert Museum and the redevelopment of the Shell Centre building in Waterloo. Stuart is UK representative of on the EC7 evolution group for the design of embedded
retaining walls and currently leads the geotechnical design of the S1 and S2 D&B packages on HS2.
