For many materials, linear elastic models do not accurately describe the observed material behaviour. A classic example of elastic deformation, and indeed, of highly elastic behavior, is a rubber band: it can be deformed to a length many times its original size, but upon release, it returns to its original shape. Some materials stretch and squash quite easily. Stretchy material stretches or can be stretched: 2. Modeling clay, on the other hand, is relatively inelastic and retains a new shape even after the force that caused it to change is no longer being exerted.

But cardboard also has a slight flexibility compared to, for example, iron. A lot of materials become brittle and inflexible when cooled. Because viscoelastic materials have the viscosity factor, they have a strain rate dependent on time. In reality, most of the materials have an elastic and a plastic region separated by a yield point, after which the stress-strain curve becomes nonlinear. The most common example of this kind of material is rubber, whose stress-strain relationship can be defined as non-linearly elastic, isotropic and While stretch fabrics are famous for fashion purposes, they come with pros and cons. , 2008). 2- Spandex or lycra. For example, 2-way stretch knits are not as resilient as 4-way stretch knits and will begin to droop after stretching. Different materials show different elastic behaviour. The examples given of flexible and rigid materials they are always relative. STRETCHY definition: 1. The change in shape must surely occur, but to the unaided eye it's imperceptible. This property is achieved by incorporating elastomeric fibers like spandex or elastane in the fabric structure, often blended with materials such as cotton fabric. Lycra FreshFX is used for products that require all-day freshness. Marbles. After a point, it may snap as well.

Polymer chains are held together in these materials by relatively weak intermolecular bonds, which permit the polymers to stretch in response to macroscopic stresses. (A) is an unstressed polymer; (B) is the same polymer under stress. This is because fabrics that do not contain elastane would ordinarily stretch and never recover, whereas any piece of fabric with an appreciable quantity of elastane – between 5% and 10% – would easily return to normal. Jul 4, 2024 · Explore the fundamentals of Hooke\\'s Law of Elasticity, which defines the linear relationship between force and displacement in elastic materials. Elastomer, any rubbery material composed of long chainlike molecules, or polymers, that are capable of recovering their original shape after being stretched to great extents—hence the name elastomer, from “elastic polymer.
