Although the SPT is close to its standardization as a mechanical testing method, there are many methodologies for the estimation of the different mechanical properties. All of them are based on the use of a correlation equation to link the SPT and the estimated mechanical property. The scattering of these correlation methods is generally great enough to make it necessary to delve deeper into the understanding of the physical behavior of the SPT. This investigation was based on previous numerical studies related with the multi-dependency with more than one mechanical property of the correlation methods for the yield strength estimation. Specifically, an optimization of the t/10 offset correlation method was designed introducing the minimum slope Slopemin of the zone III of the SPT curve in the correlation equation. This optimized t/10 offset method showed a significant reduction of the scattering between its regression surface and the material data. After completing this numerical analysis, experimental tests (tensile and SPT tests) were performed to validate the new method. application/pdf eng Elsevier Journal of Nuclear Materials. 2020, V. 534, 152177 https://doi.org/10.1016/j.jnucmat.2020.152177 Attribution-NonCommercial-NoDerivatives 4.0 Internacional http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Small punch test SPT Yield strength t/10 offset method Resistencia de materiales Ingeniería mecánica Ensayos (Tecnología) Strength of materials Mechanical engineering Testing Optimization of the t/10 offset correlation method to obtain the yield strength with the Small Punch Test info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Journal of Nuclear Materials 534 152177 THUMBNAIL Calaf-jnm_2020.pdf.jpg Calaf-jnm_2020.pdf.jpg IM Thumbnail image/jpeg 4177 https://riubu.ubu.es/bitstream/10259/8496/4/Calaf-jnm_2020.pdf.jpg ae93ff86f39653a39b5304add2cd25f5 MD5 4 LICENSE license.txt license.txt text/plain; charset=utf-8 999 https://riubu.ubu.es/bitstream/10259/8496/3/license.txt b295bcbce42e2caabeb0c623d3860c06 MD5 3 CC-LICENSE license_rdf license_rdf application/rdf+xml; charset=utf-8 805 https://riubu.ubu.es/bitstream/10259/8496/2/license_rdf 4460e5956bc1d1639be9ae6146a50347 MD5 2 ORIGINAL Calaf-jnm_2020.pdf Calaf-jnm_2020.pdf application/pdf 830139 https://riubu.ubu.es/bitstream/10259/8496/1/Calaf-jnm_2020.pdf d73a2a35518de01ebf25537ae28424d8 MD5 1 10259/8496 oai:riubu.ubu.es:10259/8496 2024-01-27 02:05:27.241 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
