Stress strain curve elastomers . Ductile vs. Brittle – Stress-Strain Curves. If a material breaks without any plastic deformation, the material is known as a brittle material. On the other hand, all ductile materials experience plastic deformation before failure.

This … WebThe modeling of materials as rigid-perfectly-plastic facilitates analysis of many problems due to the fact that bodies made from such materials satisfy two extremal principles. In turn, these extremal principles can be used to find upper and lower bounds to the limit load associated with a given boundary-value problem.
