Introduction of Compressive and Tensile Stresses in Structural Members
One of the most important things for engineers to understand when designing structures is how stresses are applied to different materials. In general, there are two types of stresses that can be applied to structural members: compressive and tensile. In this article, we’ll take a closer look at these two types of stresses and how they can affect the performance of structures.
What Is Stress and Their Types
- Stress is the body’s response to any demand
- It is a natural and normal part of life
- When a person perceives a threat, the brain signals the body to release a burst of hormones to fuel the “fight-or-flight” response
- This release of hormones increases the person’s heart rate and blood pressure, and redirects blood flow to the muscles, which all serve to increase the person’s strength and energy.
- There are different types of stress, including acute stress, chronic stress, and positive stress
- Acute stress is the most common type of stress and is the body’s response to immediate danger
- Chronic stress is a more long-term stress that can be caused by different factors, such as a demanding job or a stressful home life
- Positive stress, also known as eustress, is a type of stress that can actually be beneficial, such as when it motivates a person to meet a deadline or achieve a goal.
Why Compressive Stress Is Considered as Negative
- Compressive stress is the stress that results from a force acting on a material in a direction perpendicular to its longitudinal axis
- The force may be applied to the material by an external agent, or it may be the result of the material’s own weight.
- Compressive stress is considered to be negative because it tends to reduce the material’s ability to resist further deformation
- In other words, it makes the material more likely to fail under any additional stress that may be applied.
Conclusion
In conclusion, the compressive and tensile stresses are two of the most important stresses that act upon structural members. These stresses can cause the members to fail if they are not properly designed to account for them. by taking into account the both the compressive and tensile stresses, engineers can design stronger and safer structures.
