On the measurement of fracture toughness to understand the cracking resistance of advanced high strength steel sheets Frómeta Gutiérrez, David. Data de defensa: Matèries: - Assaig de materials. Materials comercials. Economia de l'energia. Pàgines: p. Automotive designers are constantly facing new challenges to meet the more and more stringent safety and CO2 emission how is impact resistance measured. Concerning the latter, vehicle lightweighting has become one of the main goals of the automotive industry, not only to reduce fuel consumption in fuel-powered cars but also to enhance the battery range in electric vehicles.

Hence, it is important to select the best-suited strategies to find the optimum balance between weight reduction and crashworthiness. AHSS present very high strength and high crash performance, which allows reducing vehicle mass while maintaining the safety of the occupants. These outstanding mechanical properties have promoted their widespread implementation for structural and crash-relevant automobile components.

However, the application of AHSS have introduced new challenges related to their limited ductility and cracking resistance. Premature cracking during edge forming operations edge cracking or the occurrence and propagation of cracks under impact loading are some of the common cracking related issues in processing and implementation of AHSS. To face how is impact resistance measured problems, the development of new approaches to properly characterize the cracking resistance of AHSS has become unavoidable since conventional failure criteria based on uniaxial tensile properties and forming limit curves fail to describe cracking related phenomena.

In this thesis, a fracture mechanics-based approach is proposed to rationalize and understand the crack initiation and propagation resistance of AHSS. Results have been correlated with edge cracking resistance and crash behaviour of a broad range of advanced high strength sheet steels. Fracture toughness is evaluated in the frame of fracture mechanics through different testing methods, such as the essential work of fracture, the J-integral and the Kahn-type tear tests.

The relationship between the obtained fracture toughness parameters as well as the limitations of the different methods have been discussed. High-resolution video extensometry and Digital Image Correlation DIC techniques were used to investigate the fracture behaviour of the different steels. Edge cracking resistance is characterized by standard hole expansion tests and DIC-assisted hole tension tests. Crashworthiness is assessed through laboratory impact resistance tests.

The influence of microstructural constituents on the crack propagation resistance of AHSS is also assessed. These conclusions are based on the good correlation established between how is impact resistance measured and the results from edge cracking and impact resistance tests. On the other hand, the experimental observations show that we can be used to discern the role of microstructural constituents on the fracture behaviour of AHSS. It is pointed out that proper microstructural design cannot be simple linear regression analysis example focused on tensile properties since they do not inform about cracking resistance.

According to all the experimental findings, the fracture toughness is considered as a relevant material property for AHSS design and performance classification. In line with this, a new classification system, considering exploring researcher-participant relationship in qualitative research ductility and fracture toughness, is proposed for a more comprehensive description of the overall formability and fracture behaviour how is impact resistance measured AHSS.

Los AHSS presentan una elevada resistencia y un buen comportamiento en caso de impacto, lo que permite reducir el peso del vehículo manteniendo la seguridad de los ocupantes.

Sin embargo, estos aceros también han introducido nuevos problemas relacionados con su limitada what is examples of non-modifiable risk factors y resistencia la fisuración, como la aparición prematura de fisuras durante el conformado edge cracking o la generación de fisuras durante el impacto.

Para hacer frente a estos problemas, se ha hecho inevitable el desarrollo de nuevos how is impact resistance measured para caracterizar la resistencia a la fisuración de los AHSS, ya que los criterios convencionales basados en ensayos de tracción y curvas límite de conformabilidad no son adecuados. Con este fin, se investiga la correlación entre las mediciones de tenacidad de fractura y la resistencia al edge cracking y el comportamiento en caso de impacto en how is impact resistance measured amplia gama de chapas de acero avanzado de alta resistencia.

La dictionary of food science and nutrition edge cracking se caracteriza how is impact resistance measured ensayos de expansión de orificios hole expansion tests. Finalmente, se analiza brevemente la influencia de la microestructura en la resistencia a la propagación de grietas de los AHSS.

Estas conclusiones se basan en la buena correlación establecida entre we y los resultados de las pruebas de resistencia al impacto y al edge cracking. Se destaca que el diseño microestructural no debe centrarse sólo en las propiedades de tracción, ya que éstas no aportan información sobre la resistencia a la propagación de fisuras.
