What will happens if yield strength exceed the limit?
When ever a part or material experiences a large amount of stress there will be some form of deformation. The part or material will return back to its physical shape it was in before it was stressed. If the stress on the part or material exceeds it's yield strength then it will forever alter the physical characters of the body in question (It will forever change the shape of the material because it has been strectched too far to return back to normal).
Difference between yield stress and yield strength?
Stress is a measure of the load applied to a sample relative to a cross sectional area of the sample. Strength is a quantification of the samples ability to carry a load. The terms "yield strength" and "yield stress" of a material are usually used interchangeably (correct or not). It is the stress which will just cause the material to plastically deform. If a material yields at 30,000 psi, the yield stress is 30,000 psi. If the part in question has a cross sectional area of 2 square inches, the strength at yield would be 60,000 pounds, but usually we just say the yield strength is 30,000 psi.
Is tensile strength of cold rolled steel is greater than yield stress?
For ductile materials, the yield stress is always lower than the tensile strength of the material. For brittle material they can usually be considered the same point. Steel is generally considered ductile.
What is ultimate bending strength?
It is the maximum stress at which a material will fail when subject to flexural ( moment producing) bending loads. These stresses occur a the material outer fibers.
What is the tensile strength of .375 bolt?
Tensile strength is a material propery, it does not depend on size. Look at a material chart to find its yield and tensile strenghts. Then use the stress equation, Stress = Force / Area to determine if your .375 bolt can handle the force on it. If your bolt is in shear, you need to find Shear strenghts.
What will happen to a material if the stress applied exceeds the ultimate strength?
hehe of course the material will be deform :)
What happens when stress exceeds the strength of material?
the material looses its shape
What happens to a material that undergoes stress that exceeds its strength?
If a the stress of a material exceeds the yield stress, it will not be able to return to its original length or shape once the force is removed.
What will happen to a material if the stress exceeds the ultimate strength?
It will break or fail. The type of failure will depend on how brittle/ductile it is. Brittle material will break cleanly, while ductile material will deform to varying degrees.
What causes an object to break on impact?
Internal stress exceeds the strength of the material. The cause of the stress is that the "leading edge" of the object stops while the "trailing edge" is still moving.
What will happen to a material if the stress exceeds the ultimate stress?
You usually say that the member fractures or fails at its ultimate stressDepending on the properties of the material, as stress increases, a typical metal will undergo elastic deformation, then a region of (nearly) constant plastic deformation, then strain hardening, a period of necking and then fracture.
What will happens if yield strength exceed the limit?
When ever a part or material experiences a large amount of stress there will be some form of deformation. The part or material will return back to its physical shape it was in before it was stressed. If the stress on the part or material exceeds it's yield strength then it will forever alter the physical characters of the body in question (It will forever change the shape of the material because it has been strectched too far to return back to normal).
Ultimate tensile strength?
the maximum stress which the material can bear without breaking is called the maximum tensile strength of the material
What season do earthquakes and hurricanes most often happen?
When ever the stress on the Earth's crust exceeds it's tensile strength.
What is Yield Strengths?
Yield strength is the stress at which a specified amount of permanent deformation of a material occurs. When we apply stress to a material, it deforms. Some of the deformation is plastic and the material can recover when the stress is relieved. But some deformation is permanent and the material cannot recover from it. As we apply more stress, there is more deformation. This plots on a curve in a somewhat linear, or proportional, way. But at some point, a bit more stress results in a lot more deformation, and this is the proportional limit of the material. Stress applied beyond this causes an increasing rate of deformation until the maximum or ultimate strength of the material is reached. (Beyond that it will fail completely.) Somewhere between the proportional limit and the ultimate strength of the material is the yield strength. The yield strength of a material cannot be calculated for any material. It must be arrived at through (repeated) experiment and statistical analysis. Use the link below to the related question, and the other links to related articles that explain more about yield strength.
What is the tensile strength of plywood?
It is the ultimate strength of a material subjected to tensile loading. In other words, it is the maximum stress developed in a material in a tension test.
When use proof stress?
When the stress-strain curve of a material fails to produce a clear yield strength.
