The difference between strength and toughness

Metal strength and fracture toughness are important mechanical properties for structural components.  I wrote an article that explains the trade-offs between strength and toughness and designing for applications requiring high strength and toughness.

For structural components, strength and fracture toughness are two important mechanical properties.  Yield strength is the measure of the stress a metal can withstand before deforming.  Tensile strength is a measure of the maximum stress a metal can support before starting to fracture. Fracture toughness is a measure of the energy required to fracture a material that contains a crack.
