Buy streatch fabric here >>. Glass. It is safe for most materials other than rubber to assume that the amount of deformation is proportional to the stress. This same process works for waistband elastic as well. Honorable mentions go to stretch lace, Powernet, acetate/spandex, modal/spandex, Tencel/spandex, and linen/ spandex. This stretching ability makes it a popular fabric to use in making clothes. Material elastic features are characterized by the modulus of longitudinal elasticity, E. Depending on its value, a material can be rigid (high modulus) such as in ceramic engineering, or susceptible to deformation (low modulus) such as elastomers. Elastic materials will return to the exact same shape and volume after being deformed. You have a lot of ways to get the material clean. Viscoelastic materials are used for isolating vibration, dampening noise, and absorbing shock. B. ELASTIC LIMIT. » 5 Elastic Fabric Types: What is Elastic Made of? C. Brass. D.

Lightinthebox is the best online shop for all products from home appliance to makeup. I need to make a ball which needs to bounce rather a lot. Most materials are elastic for a certain range of forces, up to the elastic limit, beyond which they are plastic. Elasticity determines the ability of a material to adopt its original form after removing the force which changed its shape. Ans: d 25. Elastomers are elastic materials that regain their original shape if they are distorted. It is the maximum stress a body can experience without being permanently deformed. When elastic is combined with polyester or other thread types, it is usually at the center of the construction and its duties are restricted to bringing the clothing item back to its original shape. So I'm guessing that DNA is the most elastic substance. Hooke attempted to write a simple rule that describes the behaviour of all materials subjected to a tensile force. Substances that display a high degree of elasticity are termed "elastic." Modulus of elasticity (or also referred to as Young’s modulus) is the ratio of stress to strain in elastic range of deformation. This is a pretty difficult question to answer. Examveda . This is especially important for load-bearing constructions. However, most SMHs as actuators have low elastic moduli and/or weak reversible bonds, which are intrinsically insufficient for desirable large energy storage and high work output, so most SMHs can only recover moderate bending, folding, and twisting deformations (23, 24). Relevance. It is so strong, it is used for tough activities like boating and other outdoor activities. Elastic Fabric 2: latex is made from rubber but that compound is difficult to sew and it is hard to wear. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles. Then there is baby elastic that is used primarily in baby clothes. Among materials with identical elastic limits, the most elastic is the one with the lowest elastic modulus. Also, it is used in most wash and wear clothing lines. The durability of this fabric means that it is very hard to shrink. Elastic fabric is a combination of materials that have elastic characteristics as well as flexible natures. B. Cotton elastic is very absorbent, and it is very soft. My question is what is quartz fibre and what makes it the most elastic material? It is the most versatile and the least expensive.

MissKittyInTheCity. Answer: Option C . Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation.Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied. Linear elastic materials must satisfy the conditions of material or Drucker stability (see the discussion on material stability in “Hyperelastic behavior of rubberlike materials,” Section 17.5.1).Stability requires that the tensor be positive definite, which leads to certain restrictions on the values of the elastic constants.
