The yield strength of a material is the stress at which the material begins to deform plastically, or permanently, under an applied load and is an important property that affects the behavior of the material under load. The yield strength is typically expressed in units of force per unit area, such as megapascals (MPa). The …

The modulus of elasticity, also known as the Young’s modulus, is a measure of the stiffness of a material and is used to describe the material’s resistance to elastic deformation under an applied load. The modulus of elasticity is defined as the ratio of the tensile or compressive stress to the tensile or compressive strain …
Hardness is a measure of a material’s resistance to deformation, indentation, or scratching and is an important property that affects the behavior of the material under different types of loading. Hardness is typically expressed in units of force per unit area, such as megapascals (MPa). There are several methods for measuring the hardness of a …

Ductility is a measure of a material’s ability to deform plastically, or permanently, under an applied load before breaking or failing. Ductility is typically expressed as a percentage of the material’s original length that it can be stretched or deformed before breaking. Materials that are highly ductile can be stretched or deformed to a large …
