Originally Answered: What's the difference between elastic and plastic deformation ? Elastic deformation: The material always returns back to it's original shape, deformation is reversible. Plastic deformation: The material will no longer return to it's original shape, permanent deformation has occured.

Elastic Limit is the maximum you can deform a body, before which there will be no permanent deformation. ... Elasticity is a property of a material, due to which, once a deforming force is removed, it returns to its original size and shape.

Main Difference – Shear Stress vs. Tensile Stress. ... The main difference between shear stress and tensile stress is that tensile stress refers to cases where a deforming force is applied at right angles to a surface, whereas shear stress refers to cases where a deforming force is applied parallel to a surface.

Ideally, flexural or bending modulus of elasticity is equivalent to the tensile modulus (Young's modulus) or compressive modulus of elasticity. In reality, these values may be different, especially for polymers.

Elastic limit is the maximum stress that can be applied without resulting in permanent deformation when unloaded. Yield point is also a stress at which there is large increase in strain with little or no increase in stress. Ony steel exhibits this type of response.

Those materials for which large amount of stress causes less amount of strain are more elastic. ... When iron and rubber are subjected to some stress(pressure) then rubber can be stretched easily but iron cannot. Hence iron is more elastic than rubber.

Importance of Yield Strength & Plastic Deformation to Civil Engineers. ... Yield stress is the stress level at the point where the material begins to have permanent deformation, i.e. yield point where the material no longer returns to its original shape and size after the release of the applied stress.

The key difference between polymers and plastics is that plastic is a specific type of polymer. Plastics are comprised of a long chain of polymers, where polymers are composed of smaller, uniform molecules.

The basic difference between young's modulus, bulk modulus, and shear modulus is that Young's modulus is the ratio of tensile stress to tensile strain, the bulk modulus is the ratio of volumetric stress to volumetric strain and shear modulus is the ratio of shear stress to shear strain.

(a) Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than the strain produced in rubber.

Being elastic means being able to be stretched, like a rubber band or a spring while being flexible refers to being able to be bent like a plastic ruler or even a wire. An object that is flexible may not necessarily be elastic as it may be able to bend but it cannot be stretched.

The elastic modulus measures the stiffness in a material, but strength is a function of the modulus. ... Remember, strength measures how much stress the material can handle before permanent deformation or fracture occurs, whereas the stiffness measures the resistance to elastic deformation.

The difference between slope and elasticity is that slope... is a ratio of two changes, and elasticity is a ratio of two percentage changes. As we move downward and to the right along a linear, downward-sloping demand curve, slope remains constant but elasticity changes.

Which accurately describes the difference between elastic and inelastic demand? Elastic demand refers to a change in demand by consumers when the price of a good or service changes, whereas inelastic demand refers to the lack of change in demand as prices change.

In metal forming context, Forming is a more generalized term involves in the shaping and fashioning of the material by plastic flow of material without adding and removal of material. Whereas Drawing is a specific metal forming/working process, which predominantly uses tensile forces to deform the material .

More heat-resistant – metals tend to have a higher melting point than plastics. Operating temperature – metal can be used in extreme hot and cold temperatures. Metal has a higher tensile strength than plastic. Stainless steel is durable and easy to clean.
