What is the reason for strain?
A strain is caused by twisting or pulling a muscle or tendon. Strains can be acute or chronic. An acute strain is caused by trauma or an injury such as a blow to the body; it can also be caused by improperly lifting heavy objects or over-stressing the muscles.
What is concept of strain hardening?
Strain Hardening is when a metal is strained beyond the yield point. An increasing stress is required to produce additional plastic deformation and the metal apparently becomes stronger and more difficult to deform. Strain hardening is closely related to fatigue.
What causes work hardening in materials?
work hardening, in metallurgy, increase in hardness of a metal induced, deliberately or accidentally, by hammering, rolling, drawing, or other physical processes. Although the first few deformations imposed on metal by such treatment weaken it, its strength is increased by continued deformations.
What are the applications of strain hardening?
Industrial Applications of Strain Hardening Anti-fatigue- Hardening can drastically improve the service life of mechanical components with repeated loading/unloading, such as axles and cogs. Machine cutting tools needs be much harder than the material they are operating on in order to be effective.
What is strain hardening and softening?
The terms cyclic strain hardening and softening are used to describe such increases and decreases in stress range, since these are accompanied by corresponding changes in indentation hardness.
What is the result of a strain?
Strains can be acute or chronic. An acute strain is caused by trauma or an injury such as a blow to the body; it can also be caused by improperly lifting heavy objects or over-stressing the muscles. Chronic strains are usually the result of overuse—prolonged, repetitive movement of the muscles and tendons.
What is cold working or work hardening?
What is Strain Hardening / Cold Working / Work Hardening? Strain hardening can also be called cold-working or work-hardening Tempering is the processing applied to the metal Cold working is an important way to increase strength in metals
