Abstract
We developed a phase-field approach to model desiccation-induced fracture in porous media. The model describes the coupling of deformation, fluid flow and fracture in partially saturated materials. Different coupling options are discussed and compared, and physically motivated improvements with respect to previous models are introduced. The discretization setting hinges upon a stabilized low-order finite element to maximize efficiency within a three-dimensional implementation. We also discuss the comparison of numerical results to predictions of semi-analytical approaches and to experimental results.
About Laura De Lorenzis
Laura De Lorenzis received her Engineering degree and her PhD from the University of her hometown Lecce, in southern Italy, where she first stayed as Assistant and later as Associate Professor of Solid and structural mechanics. In March 2013 she moved to the TU Braunschweig, Germany, as Professor and Director of the Institute of Applied Mechanics. There she was founding member and Chair (2017-2020) of the Center for Mechanics, Uncertainty and Simulation in Engineering. Since February 2020 she is Professor of Computational Mechanics at the ETH Zürich. She was visiting scholar in several renowned institutions, including Chalmers University of Technology, the Hong Kong Polytechnic University, the Massachusetts Institute of Technology (as holder of a Fulbright Fellowship in 2006), the Leibniz University of Hannover (with an Alexander von Humboldt Fellowship in 2010-2011), the University of Texas at Austin and the University of Cape Town. She is the recipient of several prizes, including the RILEM L’Hermite Medal 2011, the AIMETA Junior Prize 2011, the IIFC Young Investigator Award 2012, two best paper awards and two student teaching prizes at the TU Braunschweig. In 2011 she was awarded a European Research Council Starting Researcher Grant. She has authored or co-authored more than 120 papers on international journals on different topics of computational and applied mechanics.
Research interests
Laura De Lorenzis and her group develop models and computational frameworks to describe complex mechanical processes, with the ultimate goal of enabling computational material, process and structural design and optimization. Their research deploys modern simulation methods and develops them further to meet the ever-increasing demand for accuracy and efficiency. The group also values and pursues experimental validation and, whenever needed, develops new testing setups and techniques. The focus at this moment is especially on fracture and fatigue mechanics, contact and interface mechanics, and modeling and simulation of additive manufacturing processes. Research methods are based on multiscale and multifield modeling, high-performance computing, mechanical testing including computed tomography and the related imaging techniques, and data-driven approaches.
About the SFB 1313 Anneliese Niethammer Lecture Series
Anneliese Niethammer was the first female professor of the University of Stuttgart in 1947. The lecture series, dedicated to Anneliese Niethammer, is organised by the Collaborative Research Center (SFB) 1313 and takes place once a semester. Renowned international female researchers speak on relevant topics of current research in the research area of porous media.
