What are the Stress-strain characteristics of ductile materials?

initially there is the linear elastic region which obeys the hooks law :stress is directly proportional to the strain.
at the end of the linear elastic region the ductile material reaches the yield point beyond which any change in dimensions become permanent. the material goes through a yield plateau in which stress is constant and the strain changes.
after crossing the yield plateau the ductile material goes through the strain hardening region in which the deformation is permanent but as the region goes on the stress increases with the strain. here the strength of the ductile material increases as it is strain hardened. at a point it reaches the ultimate load point. This is the maximum load taken by the material. after which further deformation causes decrease in strength or the stress goes on decreasing finally breaking at the breaking load point. this region is called the post-ultimate region.

What are some ductile materials?
Materials that are ductile, or have the property of ductility, will stretch and deform when they are pulled, rather than breaking. Gold, silver, copper, iron, and lead are common examples of ductile materials.
How do you determine the hardness of ductile materials?
Hardness of ductile materials can be determined by following methods..... 1) Brinell Hardness Test 2)Vickers Hardness Test 3)Rockwell Hardness Test 4) Scratch hardness test
Is concrete ductile?
No, concrete is not ductile
Is stainless steel ductile or brittle?
it is ductile. For hardened stainless steel it gets less ductile, but not brittle.
Is duct tape a ductile material?
Yes, it is very ductile
What are some ductile materials?

How do you spell matiles?
Some likely possibilities: METALS - elements having conductive or ductile characteristics MATERIALS - products used in a process or construction
What type of compound is ductile nonpolar or polar?
Several metals can be ductile materials.
What are the types of high temperature degradation of materials?
ductile is the main one type in ductile
What is non-ductile?
Materials like gold and copper can be bent; they are malleable or ductile. Materials that are brittle and break easily are non-ductile. Conventional concrete is non-ductile (and breaks under stress of earthquakes)(or other tensile challenge). Metal (steel) mesh or synthetic fibers are added to concrete to make it more ductile.

Max principle stress theory is valid for which material?
For materials that are brittle rather than ductile. For ductile :max shear stress theory would be more suitable
Why it is eassy to weld hard material than ductile?
it is not easy to weld hard materials....it always difficult to hard materials.....

What theory of failure is used for ductile materials?
For ductile materials, teh VonMises theory is used; it combines tension and shear stresses in a different way than principal stress, which is used for brittle materials. In either case, its value is compared to the normal (tension/compression) stress allowable for the particular material.
Is ductile a non metal or metal?
Ductile metals are metals that5 can be shaped and pulled. Gold is a example of a ductile metal so in other words, yes it is a type of metals. Ductility is a property of some metals. It is also a property of materials other than metal.
What are 4 characteristics of most metals?
Metals tend to be lustrous, ductile, malleable, and good conductors of heat and electricity.
