Hardness and Brittleness are in game underwhelmed, hardness is a combanation of the moduli and yield/tensile strength, the moduli are measures of how much force the material can take and still bounce back (youngs is two opposed forces, shear is two forces that are not in line with each other and bulk is force from all angles and sides, don't quote me on this I might be wrong) yield strength and tensile strength is how much force untill the material breaks or suffers permenate damage

Hardness and Brittleness are in game underwhelmed, hardness is a combanation of the moduli Only applies to elastic deformation Which marks where elastic deformation ends Hardness is compressive, not tensile Materials can deform plastically without fracturing, they are two different things. There's no material property in the game that says how much plastic stain a material can take before fracture.

At least that's what the in game infolink described.

Yield strength is where material starts to deform plastically, and ultimate tensile strength is where a material fractures - the difference between the two is a rough measure how far a material will deform plastically before it fractures, e.g. tungsten carbide has equal yield and ultimate strength, both 530 MPa, so it will shatter immediately upon starting to deform plastically.

UTS is not fracture, it's the point where necking begins for ductile materials whereas fracture is when the whole thing breaks in 2 but it really doesn't matter considering that its basicly over by that point. Here's a nice stress-strain graph from the Internet: Oh and ductile materials are usually tougher, like how copper is tougher(not->stronger) than steel.
