YIELD CRITERION Meaning and
Definition
-
A yield criterion refers to a set of mathematical equations or conditions used to determine when a solid material subjected to external forces will undergo plastic deformation and yield. It provides a criterion or rule that helps engineers and researchers assess the material's ability to withstand stress before permanent deformation occurs.
In engineering and materials science, yield is the point at which a material initiates plastic deformation, meaning it undergoes a permanent change in shape or size when subjected to external forces or loads. The yield criterion aims to define the conditions under which this plastic deformation begins.
By utilizing various mathematical equations and models, a yield criterion quantitatively defines the relationship between the stress applied to a material and the resulting deformation. These models consider factors such as the material's mechanical properties like strength, ductility, and brittleness.
Different types of materials may have different yield criteria due to their unique characteristics. Metals, for example, tend to exhibit yielding in a ductile manner, while brittle materials may experience failure without significant plastic deformation. Therefore, yield criteria allow engineers and scientists to predict and understand how materials will behave under specific loading conditions and design structures and components accordingly.
Overall, a yield criterion serves as a valuable tool in the field of materials science and engineering, enabling professionals to assess the safe operating limits of materials, determine their strength and deformability, and make informed decisions about their application in various industries including construction, automotive, aerospace, and many others.

Etymology of YIELD CRITERION
The etymology of the word "yield criterion" can be understood by breaking it down into its constituent parts:
1. Yield: This word comes from the Old English word "gieldan", which means "to pay or give back". It can also be traced back to the Proto-Germanic word "geldan", which means "to pay or perform". The term "yield" in the context of mechanics refers to the point at which a material or structure experiences permanent deformation or failure.
2. Criterion: This word comes from the Greek word "kriterion", which means "a means of judging or deciding". It can be traced back to the Greek word "krinein", which means "to separate or judge". The term "criterion" in the context of engineering or mechanics refers to a set of conditions or limits upon which a judgment or decision is based.
