Maggioli, Filippo (author)Finite Element Methods (FEMs) are widely employed for damage simulation in composites, with the Cohesive Zone Model (CZM) being particularly favored for its robustness and scalability. Despite the CZM's mesh-dependent nature, the Discontinuous Galerkin Cohesive Zone Model (DG/CZM) formulation allows for relatively arbitrary crack propagation...master thesis 2024

Effect of temperature on the healing capacity and mechanical properties of Ti2AlC MAX phase ceramicsSuh, Minji (author), Lee, Dong Heon (author), Sloof, W.G. (author), Lee, Kee Sung (author)In this study, the self-healing capacity of Titanium Aluminum Carbide (Ti<sub>2</sub>AlC, MAX phase) was investigated. Bulk coin samples were fabricated to evaluate the self-healing capacity at different temperatures (1000, 1200, and 1400°C). The extensive self-healing capacity of Ti<sub>2</sub>AlC was confirmed on larger quasiplastic damage ...journal article 2024

Jumelet, Daan (author), van Gent, M.R.A. (author), Hofland, Bas (author), Kuiper, C. (author)Physical model tests have been performed to study static stability of rock-armoured mild slopes. Current stability design formulae for steeper rock-armoured slopes focus on plunging and surging waves. Slopes of 1:6 and milder usually have more spilling breakers which decreases the load. Also, on mild slopes displaced rocks more often remain...journal article 2024

Li, Tianzhi (author), Chen, Jian (author), Yuan, Shenfang (author), Zarouchas, D. (author), Sbarufatti, Claudio (author), Cadini, Francesco (author)Fatigue damage prognosis always requires a degradation model describing the damage evolution with time; thus, the prognostic performance highly depends on the selection of such a model. The best model should probably be case specific, calling for the fusion of multiple degradation models for a robust prognosis. In this context, this paper...journal article 2024

Xu, Fuqiang (author), Shi, Yu (author), Song, Xianzhi (author), Wu, Wei (author), Song, G. (author), Li, Shuang (author)The development of hot dry rocks (HDRs) is of great significance to adjusting energy structure, alleviating energy shortage, reducing pollution, etc. Low-permeability granite is the predominant rock type in deep HDRs, making fractures the primary pathways for fluid circulation and heat extraction. The production of HDRs is significantly...journal article 2024
