Resumo: | |||||||||||||
Fracture toughness or resistance to fracture is the critical stress concentration factor
of a crack that leads to fracture, while impact resistance refers to a material’s ability to
withstand a sudden or impact load, even in the absence of cracks. Both properties are
crucial for understanding the behavior of materials in real-world applications, allowing
for better design of parts and components according to their intended function.
There are some correlations between toughness and impact resistance (in the
absence of cracks) for metals, despite this being a highly relevant topic in various fields
of engineering and materials science. Understanding this interaction is fundamental for
developing safer, more durable, and efficient materials that can be applied in a wide range
of uses.
In this study, extensive research will be conducted to collect empirical data on
Charpy impact resistance, fracture toughness, and elastic modulus. Using this
information, different correlation models will be applied to derive toughness values from
Charpy and elastic modulus data.
The purpose of this work is to evaluate the reliability and accuracy of the different
correlation methods by comparing theoretical and experimental fracture toughness values.
By calculating the relative error of each model for each studied material, it will be possible
to assess the different estimates and analyze which type of material is best suited for their
application.
