Mechanical Properties of Metals: Toughness and Strength

Elastic materials return to their initial state after stress is applied and then removed.

Modulus of elasticity quantifies a material's resistance to permanent deformation.

Anelasticity describes a material's behavior when undergoing plastic deformation.

Yielding and yield strength occur at the elastic limit of a material.

Tensile strength measures a material's resistance to breaking under compression.

Ductility refers to a material's ability to sustain a large temporary deformation without fracturing.

Plastic deformation occurs when the applied load has compressed and rearranged the atomic bonds.

Silicates are ceramics that consist of arrangements of Silicon and Oxygen atoms.

Ionic bonding is present in compounds like Diamond and SiO2.

Silica glasses are always formed as crystalline solids.

Ceramic structures are primarily formed by metallic bonding.

Higher density clay products typically exhibit better insulating properties.

Mechanical properties of metals are defined independently of material shape and size.

Toughness is a measure of a material's resistance to surface deformation.

Metals are relatively dense compared to ceramics and polymers.

Metals and their alloys have randomly arranged atoms.

Hooke's Law states that the strain of a material is proportional to the applied stress within the elastic limit.

Ductility is a material's ability to be hammered thin without breaking.
