Song, G. (author), Roubinet, Delphine (author), Wang, Xiaoguang (author), Li, Gensheng (author), Song, Xianzhi (author), Tartakovsky, Daniel M. (author)Fracture distribution plays a significant role in the behavior of subsurface environments, affecting such activities as geothermal production, exploitation and management of groundwater resources, and long-term storage of nuclear waste and carbon dioxide. A key challenge in these and other applications is to estimate the fracture network...journal article 2023

Coraddu, A. (author), Oneto, Luca (author), Li, Shen (author), Kalikatzarakis, Miltiadis (author), Karpenko, O. (author)In this paper, for the first time, a three-step approach for the optimal design of stiffened panels accounting for the ultimate limit state due to welding residual stress is developed. First, authors rely on state-of-the-art analytical approaches coupled with recently data-driven nonlinear finite element methods surrogates characterized by...journal article 2023

Lin, Chaoning (author), Li, Tongchun (author), Chen, Siyu (author), Yuan, Li (author), van Gelder, P.H.A.J.M. (author), Yorke-Smith, N. (author)Dam safety monitoring has become an important topic and is critical for evaluating a dam's safety status. This study focuses on identifying the mechanical properties of a concrete dam from long-term viscoelastic deformation monitoring data. A novel inversion framework is proposed in which a surrogate model, instead of the finite element model,...journal article 2022
