What is a ductile stress-strain curve?
A ductile stress-strain curve depicts a material's ability to undergo significant plastic deformation before fracturing, characterised by yielding, strain hardening, and necking phenomena.
How is ductility shown on a stress-strain curve?
Ductility is shown on a stress-strain curve by the elongated plastic deformation region after the elastic limit, often accompanied by necking before fracture.
What is stress-strain curve for ductile and brittle material?
A stress-strain curve for ductile materials typically shows gradual plastic deformation after the elastic region, while for brittle materials, it exhibits minimal plastic deformation and sudden failure.
Which material is more ductile in stress-strain graph?
In a stress-strain graph, materials with longer plastic deformation regions and significant necking are more ductile.
Which material is more ductile?
A material that can undergo greater plastic deformation before breaking is considered more ductile.
