Difference between elastic anelastic and plastic deformation?

Answer 1

In case of elastic deformation when the applyed stress disappears, the material returns in its initial form. In case of plastic deformation a remaining shape change occurs.

Until a stress value - what is property of individual material - called flow stress, the material deforms elastically, afterwards plastically.

Answer 2

The economic concept of elasticity measures how buyers and sellers respond to shifts in market conditions, such as price changes. The terms "elastic" and "inelastic" describe how the level of supply or demand shifts in response to a change in price.

IDENTIFICATION:If a change in price leads to sharp shift in demand or supply for a particular good, that good is said to be "elastic." If a price change results in little or no change in the level of supply or demand, the good is "inelastic."

SIGNIFICANCE:Elastic goods are, therefore, highly responsive to changes in price, while inelastic goods show little response.

SIZE:Economists calculate elasticity as the percent change in quantity (supplied or demanded) divided by the percent change in price. If the resulting number is greater than 1, the supply or demand of the good is considered elastic. If it is less than 1, it is inelastic.

EFFECTS:Whether the demand or supply of a particular good is elastic or inelastic depends in part on how essential it is to most consumers. Goods that are necessities for consumers everyday lives are more inelastic. Consumers continue to purchase such goods, despite price increases.

CONSIDERATIONS:Demand is more elastic if there are substitutes for a particular product or if it is considered a luxury by most consumers.
