; Silva, Samuel da ; Alves, Mariana Pimenta ; Cimini Junior, Carlos Alberto ; Universidade Federal de Minas Gerais - UFMG This study compares two widely used failure theories for characterizing composite materials: the Tsai-Wu and Tsai-Hill failure criteria. The paper’s main objective is to evaluate the performance of both criteria in a high-pressure vessel design project, taking into account uncertainties in material properties at the lamina level and in the internal pressure applied to the vessel. The analysis of histograms of failure index fluctuations reveals that, contrary to a purely deterministic approach, each failure criterion can be more or less conservative when there is variability in the system due to different factors. Additionally, a global sensitivity analysis using Sobol indices was conducted to determine the contributions of individual inputs to the output uncertainty. This probabilistic approach emphasizes the importance of considering uncertainty analysis to design structures that are both safer and more cost-effective.ItemDado de pesquisa Efeitos histológicos, gênicos e endócrinos da temperatura na maturação de Astyanax lacustris (Characiformes: Characidae)(2024-01-30) Branco, Giovana Souza; Veríssimo-Silveira, Rosicleire ; USP ItemDado de pesquisa Variação do aporte térmico na soldagem híbrida GTAW/Laser Nd:YAG pulsado do aço UNS S32750 com adição de nitrogênio ao gás de proteção(2023-06-20) Videira, Arthur Moraes e ; Universidade Estadual Paulista (Unesp)ItemDado de pesquisa Ecologia trófica e biomarcadores isotópicos e fisiológicos de espécies de peixes silvestres associados a pisciculturas em tanques-rede(2023-02-28) Ramos, Igor Paiva; Universidade Estadual Paulista (Unesp) ItemDado de pesquisa Megaplatypus mutatus (Chapuis) (Curculionidae: Platypodinae) in a Khaya grandifoliola (Meliaceae) plantation in Brazil(2022-03-16) Flechtmann, Carlos Alberto Hector; Universidade Estadual Paulista (Unesp) ItemDado de pesquisa Acute and chronic effects of temperature on membrane adjustments in the gills of a neotropical catfish(2020-09-16) Ribeiro, Cristiéle da Silva; Universidade Estadual Paulista (Unesp)
