Elastic bands, especially waistband type material becomes brittle and breaks over time. This mainly happens when the internal elastic fibers in the band break gradually, from simple age. This process happens in as few as 5 years. The external fabric material that surrounds the underlying elastic fabric remains whole so it appears that the waistband has been stretched out intentionally or by some other unforeseen force. You can have a perfectly lovely skirt or skirts in the closet and then one day when you get them out again the waistbands appear abnormally large. This phenomenon is called molecular degeneration and happens all the time. So the next time you find some pants, a skirt, or even some socks that appear to have been vandalized while lying untouched in closet; please remember that molecular degenerationis the culprit and that your neighbor Mr. Jones probably had much better things to do with his time anyway.

What goes back into its original shape after being stretched?
Elastic or Rubber
Why do hair bands break?
Hair band break due to over stretching causing fatigued elasticity. or if they are the ones with the metal piece the metal will actually cut the fabric and elastic inside not only that but your hair also.
What is the difference of the elasticity of a material and its ultimate strength?
The elasticity of a material is the measure of it's elastic properties, how bendable it is. where as it's ultimate strenght is the force which you require to be able to break that material into 2
What if there are no elasticity?
if there is no elasticity means...there will be no deformation in shape and size...and one more thing is if we try to change the shape of the object and no elasticity means the object will break...
What can happen when rocks pass their elastic limit break and snap in elastic rebound?
Earthquakes will happen.
What happens to the elastic band when the force is increased?
The elastic band will start to wear out and eventually break.
How can you stretch elastic waistbands that are too tight?
The possibility of expanding an elastic waistband depends on a couple of things. First, does the rest of the garment fit (bust, hips)? Secondly, is the elastic in the waistband loose or sewn in place. If the elastic is loose, the process will be much easier: in the inside of the garment find a place where you can open the casing about 2"-3" so you can gain access to the elastic; pull out a loop of the elastic; secure the elastic on both sides of the opening with pins so the elastic doesn't slip back in the casing; cut the elastic; add a piece of elastic to expand your waistband, remembering to allow approximately 1/2" of overlap on both ends & sew securely; now you can remove the pins securing the elastic & allow the elastic to slip back into the casing; stitch the casing closed. However, if your waistband elastic is stitched in place all the way around, as is the case with many ready made garments, you will have to remove all the stitching first before adding more elastic, remembering to allow approximately 1/2" of overlap on both ends; carefully pin the elastic back in place and resew in place with an elastic stitch that will not break but stretch with the elastic.
What can happen when rocks pass their elastic limit break and snap back in elastic rebounds?
Earthquakes will happen.
A bending and streaching rock will break when it reaches this point?
elastic limit
A bending streaching rock will break when it reaches this point?
elastic limit
What happens when an object is stretched beyond its elastic limit?
The rock will break because it can be stretched no farther. An object stretched beyond its elastic limit may be deformed (adopt a new permanent resting shape) or break.
Does something have less elasticity when it is colder?
Yes, that is generally the case. When things get colder they become brittler. Brittle objects tend to break rather than deform and rebound. If you submerged a rubber ball in liquid nitrogen for a few moments and then dropped it from a height onto a rigid surface, it would shatter, not bounce. (Note that brittleness is not the same as rigidity. Objects can be rigid and elastic. For example, a steel girder is rigid and elastic.)
