Dear all,

it is said that, Toughness, in contrast to resilience, is how much energy can be absorbed and still keep going. In the case of materials, the amount of energy that the material can absorb plastically before fracturing is the toughness.In the figure below, we can see that a material can have a high tensile strength (ceramics) and yet have a small toughness. In addition, materials can be extremely ductile (unreinforced polymers) and also have a small toughness. So, a large toughness (metals) is obtained by having a high tensile strength and a high ductility. My question is, can this be applied to soil diagrams as well? Do you know any paper that addresses this?
