Stress vs strain curve for ductile material

WebMar 15, 2024 · Ductile materials can absorb a significant amount of energy through the ability to yield. This permits the material to endure a significant amount of plastic deformation before fracture. A typical stress-strain curve of a ductile material would include the stress-strain curve stages discussed above. WebIt is possible to distinguish some common characteristics among the stress-strain curves of various groups of materials. On this basis, it is possible to divide materials into two broad categories; namely: Ductile Materials. Ductility is the ability of a …
