It appears in armor form in The Elder Scrolls IV: Oblivion. It appears as a cyan metal used to make armor and weapons in MapleStory. Mythril is also depicted as a teal-color metal used to craft armor, weapons, and tools in Terraria. Moustachium Team Fortress 2: Yellow metal bars given to people who gained achievements in the game SpaceChem. It ...
Toughness is the strength with which the material opposes rupture. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. This measure of toughness is different from that used for fracture toughness, which describes the capacity of materials to resist fracture. [2]
The toughness of a material is the maximum amount of energy it can absorb before fracturing, which is different from the amount of force that can be applied. Toughness tends to be small for brittle materials, because elastic and plastic deformations allow materials to absorb large amounts of energy. Hardness increases with decreasing particle size.

In fracture mechanics, a crack growth resistance curve shows the energy required for crack extension as a function of crack length in a given material.For materials that can be modeled with linear elastic fracture mechanics (LEFM), crack extension occurs when the applied energy release rate exceeds the material's resistance to crack extension .
In fracture mechanics, the energy release rate, , is the rate at which energy is transformed as a material undergoes fracture.Mathematically, the energy release rate is expressed as the decrease in total potential energy per increase in fracture surface area, [1] [2] and is thus expressed in terms of energy per unit area.
Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness.
The toughness in a composite with ductile phase toughening can also be shown using stress intensity factor, by linear superposition of the matrix and crack bridging based on solutions by Tada. [18] This model can predict behavior for small-scale bridging (bridge length << crack length) under monotonic loading conditions, but not large scale ...
