What strain or pressure in a material due to forces acting on it?
Stress
What is relastion between strees and strain?
no because stress depends on the force and area of the element
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.
Why the engineering stress-strain curve in shear is the same as the true stress-strain curve?
The engineering stress-strain curve in shear is the same as the true stress-strain curve because, in shear, the definitions of stress and strain do not change significantly with the material's deformation. True stress accounts for the instantaneous area under load, while engineering stress uses the original area; however, in shear, the relationship remains linear up to the yield point, and the area reduction effect is minimal for typical shear tests. Thus, both curves reflect the same material behavior in shear deformation, leading to equivalent representations.
What are the Stress-strain characteristics of ductile materials?
initially there is the linear elastic region which obeys the hooks law :stress is directly proportional to the strain. at the end of the linear elastic region the ductile material reaches the yield point beyond which any change in dimensions become permanent. the material goes through a yield plateau in which stress is constant and the strain changes. after crossing the yield plateau the ductile material goes through the strain hardening region in which the deformation is permanent but as the region goes on the stress increases with the strain. here the strength of the ductile material increases as it is strain hardened. at a point it reaches the ultimate load point. This is the maximum load taken by the material. after which further deformation causes decrease in strength or the stress goes on decreasing finally breaking at the breaking load point. this region is called the post-ultimate region.
How to find strain from stress in a material?
To find strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Young's Modulus is a measure of the stiffness of a material. By dividing the stress applied to the material by its Young's Modulus, you can calculate the resulting strain.
How can one calculate strain from stress in a material?
To calculate strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Stress is the force applied to the material, and Young's Modulus is a measure of the material's stiffness. By dividing the stress by the Young's Modulus, you can determine the amount of deformation or strain the material undergoes under the applied stress.
Why stress increased again after lower yield point?
hi dear, yes its true that stress increases after lower yield for ductile material. it happens due to reason of strain hardening. strain hardening is the property of the material with which the grain structures presents in the body forms bond between them. so in order to break that bonds, the stress increases after lower yield point..
How to calculate strain energy in a material?
To calculate strain energy in a material, you can use the formula: Strain Energy 0.5 x Stress x Strain. Stress is the force applied to the material, and strain is the resulting deformation. Multiply stress and strain, then divide by 2 to find the strain energy.
How to calculate stress from strain in a material?
To calculate stress from strain in a material, you can use the formula: stress force applied / cross-sectional area of the material. Strain is calculated by dividing the change in length of the material by its original length. By using these formulas, you can determine the stress experienced by a material when subjected to a certain amount of strain.
How to find strain in a material under stress?
To find the strain in a material under stress, you can use the formula: Strain Change in length / Original length. Measure the change in length of the material when it is under stress and divide it by the original length of the material. This will give you the strain value.
How to calculate strain in a material under stress?
To calculate strain in a material under stress, you can use the formula: Strain Change in length / Original length. This formula helps you determine how much a material deforms under stress.
How does the strain experienced by a material relate to the stress applied to it?
The strain experienced by a material is directly related to the stress applied to it. When stress is applied to a material, it causes deformation or change in shape, which is known as strain. The relationship between stress and strain is described by the material's elastic properties, such as Young's Modulus. This relationship helps determine how a material will respond to external forces.
What is the equation that relates strain to stress in a material under deformation?
The equation that relates strain to stress in a material under deformation is known as Hooke's Law, which is expressed as stress Young's Modulus strain.
How to calculate strain from stress?
To calculate strain from stress, you can use the formula: Strain Stress / Young's Modulus. Stress is the force applied to an object, while Young's Modulus is a measure of the stiffness of the material. By dividing the stress by the Young's Modulus, you can determine the strain, which is the amount of deformation the material undergoes in response to the stress.
What does the strain vs stress graph reveal about the relationship between strain and stress in a material under mechanical loading?
The strain vs stress graph shows how a material responds to mechanical loading. It reveals that as stress increases, strain also increases, but not necessarily in a linear manner. The relationship between strain and stress can vary depending on the material's properties and behavior under different loading conditions.
What is the relationship between volume strain and the deformation of a material under stress?
Volume strain refers to the change in volume of a material when it is subjected to stress. When a material is deformed under stress, it can experience volume strain, which is the result of the material's particles moving closer together or farther apart. The relationship between volume strain and deformation is that as the material deforms, its volume may change due to the stress applied to it.
