What is another term for strain?
Strains are tears in the muscle. Sometimes called pulled muscles, they usually occur because of overexertion or improper lifting techniques.
Is there any difference between work hardening and strain hardening?
In strain hardening hypothesis, the size of the yield locus is assumed to beindependent of the third invariant.In work hardening hypothesis, the size of the yield locus is assumed to depend on the total plastic work done (per unit volume) to achieve the present state of plastic deformation since last annealinfor isotropic hardening Both are same.
What happens to strain when stress is increased in a material?
It also increases. It increases linearly with stress in the elastic range, then increass more rapidly once the material is plastic ( yielded).
What is strain to failure?
strain-to-failure
What is an elastic perfectly plastic material?
HI!!!!check out my answer....The difference between the two is....The plastic deformation will occur where pressures are relatively high and the strain rate relatively low. During plastic deformation, the materials flow and changes in shape will be permanent. While,The elastic deformation will change shape in response to a stress, then snap back into it's original shape if the stress is removed. (in other words, the strain is recoverable)IN short word...THE PLASTIC DEFORMATION ARE PERMANENT AND THE ELASTIC DEFORMATION WILL GO BACK TO ITS ORIGINAL SHAPE.ROCEL TADINA1- newton
How to calculate plastic strain in a material under deformation?
To calculate plastic strain in a material under deformation, you can use the formula: Plastic Strain Total Strain - Elastic Strain. Plastic strain is the permanent deformation that occurs in a material after it has exceeded its elastic limit. It is important to consider when analyzing the behavior of materials under stress.
What is the formula to calculate the total strain experienced by a material under a given load?
The formula to calculate total strain is: Total Strain Elastic Strain Plastic Strain. Elastic strain is the initial deformation of the material under load, while plastic strain is the permanent deformation after the material reaches its yield point.
Which type of strain permanently changes rocks?
Plastic strain, which occurs under high temperatures and pressures, can permanently change rocks by causing them to deform without breaking. This type of strain can lead to the development of new minerals and structures within the rock.
Why stress decreases after the plastic range in stress strain graph?
Strees decreases after the plastic range because the material has releived the strees through movement.
Are all minerals brittle?
This depends on the confining pressure, the temperature and the strain rate applied to the mineral. In general for minerals (and other materials), the lower the rate of strain, the more likely ductile or plastic creep deformation will occur. The higher the strain rate, the more likely brittle deformation is to occur. As the confining pressure increases, an objects shear strength will increase (this usually coincides with a greater depth of burial) and due to the earth's thermal gradient an increase in temperature. As the shear strength increases, brittle failure is less likely and the higher temperature means that plastic deformations or creep are more likely to occur.
Strain energy definitions?
Strain energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy. Some energy may be lost in plastic deformation of the member and some may be converted into heat instead of stored as strain energy, but the rest is recoverable. A spring is an example of a storage device for strain energy.
What is the effect of springback concept on plastic deformation?
Springback means Recovered elastic strain on material after the load is removed.
What is a strain like a muscle strain?
A strain is when you tear the muscle tissue slightly by over-stretching it. They occur when you put too much stress on the muscle - for example, by trying to lift something too heavy or by twisting too far.
What is the relationship between steric strain and torsional strain in organic molecules?
Steric strain and torsional strain are both types of strain that can occur in organic molecules. Steric strain is caused by repulsion between bulky groups on adjacent atoms, while torsional strain is caused by the resistance to rotation around a bond due to the presence of bulky groups. These two types of strain are related because they both result from the presence of bulky groups in a molecule, and they can both contribute to the overall instability of the molecule.
What is residual strain?
Residual Strain is the same thing as permanent strain, as in permanent strain in a beam. If you refer to a stress vs strain plot, you'll see that this relationship in metals is linear up until the yield point where the metal plastically deforms. After stress slightly decreases due to this yielding, It will continue to increase, along with strain but on a more curve-shaped line. When stress is removed from the metal, it will slowly decrease back down to 0, but there will be an offset in the strain. The distance from where strain equals zero to this new point along the axis is the the residual strain left in the metal due to plastic deformation.
Are there less chances of survival in plastic surgeries?
no, most of the plastic surgeries are non lethal. In few cases complications might occur.
What are examples of elastic spring force?
If you stretch a rubber band then release it, it will return to its original shape. That is by definition elastic strain. Anything that returns to its original shape after being affected by force underwent elastic strain. If it is permanently deformed (ie you bent a paperclip out of place and it wont return to its original shape) then it passes the elastic strain region and suffered plastic strain.
