Difference between yield strength and tensile strength
Introduction
Mechanical engineering is a branch of engineering that is dedicated to the study of the mechanics of solids and its application in the design and manufacture of machines and structures. The strength of materials is a fundamental topic in this discipline, and in this article we are going to talk about the difference between performance strength and tensile strength.
Tensile strength
The tensile strength of a material is its ability to withstand a force that tends to stretch and elongate it. That is, it is the maximum force that the material can withstand before breaking or fracturing. Tensile strength is expressed in pressure units, such as megapaschal (MPa) or kilopaschal (KPa).
Example of tensile strength
An example of the importance of tensile strength is the design of a suspension bridge. The bridge cables must be able to support the weight of the deck and the vehicles traveling on it without breaking. For this reason, cables are usually made of high tensile strength steel.
performance strength
Yield strength, on the other hand, is the amount of stress a material can withstand without permanently deforming. That is, it is the maximum stress that the material can withstand. without suffering a plastic deformation. Yield force is also expressed in units of pressure.
Performance Strength Example
An example of the importance of yield strength is the design of a part that must withstand a constant load over time. If the part does not have sufficient performance strength, it will progressively deform until it finally breaks. Therefore, it is important to know the performance strength of the materials used in the manufacture of mechanical parts.
Conclusion
In summary, tensile strength and yield strength are two fundamental concepts in material strength. Both properties are important in different contexts, and it is important to know them in order to design structures and mechanical parts that are safe and durable. By knowing the tensile strength and yield strength of the materials being used, you can ensure that products meet safety and quality standards.
