In this post, we will see and briefly compare the Stress-strain curves of Brittle material, ductile material & Elastomers.
Stress-strain curve of Brittle material: The plastic region between E and C is small for brittle material and it will break soon after the elastic limit is crossed. (example: glass)
Stress-strain curve of ductile material: The materials of this type have a good plastic range and such materials can be easily changed into different shapes and can be drawn into thin wires. (example: copper)
Stress-strain curve of Elastomers: For elastomers, the strain produced is much larger than the stress applied.
Such materials have no plastic range and the breaking point lies very close to the elastic limit. Example: rubber.
