Rigid-Plastic Material
A material that undergoes no deformation until its yield point is reached and then flows at a constant stress is called a rigid-plastic material. This type of material is commonly found in metals and is characterized by its ability to deform plastically without any increase in stress.
Yield Point
The yield point of a rigid-plastic material is the point at which the material begins to flow plastically. At this point, the material undergoes permanent deformation and its stress-strain curve becomes non-linear.
Constant Stress Flow
After the yield point, a rigid-plastic material will flow at a constant stress. This means that the stress required to continue the deformation of the material remains constant, regardless of the strain that has occurred.
Advantages of Rigid-Plastic Materials
Rigid-plastic materials have several advantages over other materials. They are strong and durable, making them useful in a variety of applications. They are also able to undergo significant plastic deformation without fracturing, making them useful in the construction of structures that need to withstand high loads.
Applications of Rigid-Plastic Materials
Some common applications of rigid-plastic materials include:
- Structural steel in buildings and bridges
- Aluminum alloys in aircraft and automotive parts
- Copper in electrical wiring
Conclusion
In conclusion, a rigid-plastic material is a type of material that undergoes no deformation until its yield point is reached and then flows at a constant stress. This type of material is commonly found in metals and has several advantages over other materials. It is strong, durable, and able to undergo significant plastic deformation without fracturing.

My Ans is C..ITS SAY NO DEFORMATION UNTILL YIELD I.E RIGID THEN CONSTANT FLOW OVER SAME STRESS SO PLASTIC..IN STRAIN HARDENING STRESS INCREASE WHILE INCREASE IN STRAIN..
