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.
What is Baushchinger effect?
The Bauschinger effect refers to a property of materials where the material's stress/strain characteristics change as a result of the microscopic stress distribution of the material. An example is an increase in tensile yield strength at the expense of compressive yield strength.
Why the actual strength of a metal is lower than its predicted ideal strength?
Because in theory we study regarding a perfect material but in reality the material will have many imperfections which decreases the stress required to deformed a material.
Best book on strength of material?
strength of material refers to the ability of a material to withstand an applied stress without failure.the material"s strength is dependent on its microstructure.Strength is considered in terms of compresive strength, tensile strength, shear strength,namely the limit states of this strength.The term of strength of materials most often refers to various methods of calculating stesses in structural members, such as beams,columns and shafts.
Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
What happens when stress exceeds the strength of material?
the material looses its shape
What happen when stress exceeds the strength of a material?
the material looses its shape
Ultimate tensile strength?
the maximum stress which the material can bear without breaking is called the maximum tensile strength of the material
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 applied exceeds the ultimate strength?
hehe of course the material will be deform :)
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.

When use proof stress?
When the stress-strain curve of a material fails to produce a clear yield strength.
What is Baushchinger effect?
The Bauschinger effect refers to a property of materials where the material's stress/strain characteristics change as a result of the microscopic stress distribution of the material. An example is an increase in tensile yield strength at the expense of compressive yield strength.
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.
What is the definition of tensile strength?
It is the maximum stress a material can withstand while being strteched.
Why the actual strength of a metal is lower than its predicted ideal strength?
Because in theory we study regarding a perfect material but in reality the material will have many imperfections which decreases the stress required to deformed a material.
