Study Notes

Discontinuity Definition

Discontinuity refers to an interruption in the typical structure of a material.
It signifies a lack of homogeneity in the material's characteristics.

Characteristics of Discontinuity

Can affect mechanical, metallurgical, or physical properties of a material.
May include variations in density, composition, or structure.

Relationship with Defects

A discontinuity may result from a defect in the material, such as cracks or voids.
Not all discontinuities are considered defects; some may have no significant impact on functionality.
