Occurs when noticeable necking starts ceramics.
Ceramic vs metal stress strain curve.
With a very short elastic region but highly capable of supporting huge stresses.
1 requires further explanation.
The zone where a material will return to its original shape for a given amount of stress toe region applies to a ligaments stress strain curve.
2 stress strain curve for ceramics.
The last two indicate ductility.
The first two are strength parameters.
1 metals al alloy stress strain curve.
Elastomers are the ones that strains more w a lower stress.
Derived from axially loading an object and plotting the stress verses strain curve.
The engineering stress strain curve does not give a true indication of the deformation characteristics of a metal because it is based entirely on the original dimensions of the specimen and these dimensions change continuously during the testing used to generate the data.
Occurs when polymer backbones are aligned and about to break σ y engineering typical response of a metal ts stress engineering strain.
Stress vs strain curve.
The general shape of the engineering stress strain curve fig.
Represents straightening of the crimped ligament fibrils.
The parameters which are used to describe the stress strain curve of a metal are the tensile strength yield strength or yield point percent elongation and reduction of area.
And finally analogous to ceramics are the stiff fibers and rigid plastics.
