Explanation:
During a tensile test, the material is subjected to a gradually increasing load until it reaches its breaking point. Near the elastic limit zone, the material behaves elastically, meaning that it will return to its original shape when the load is removed. However, the material also undergoes plastic deformation, which means that it will not completely return to its original shape after the load is removed.

Tensile Stress
Tensile stress is the ratio of the applied load to the original cross-sectional area of the material. In the elastic limit zone, the material will experience a linear relationship between stress and strain. This means that the tensile stress will increase in proportion to the applied load, and the material will deform elastically.

Tensile Stress Near Elastic Limit Zone
However, near the elastic limit zone, the material will begin to undergo plastic deformation. This means that the material will deform permanently, and the tensile stress will begin to decrease at a faster rate than the applied load. This happens because the material is becoming more resistant to deformation due to the formation of dislocations and other defects in its crystal structure.

Conclusion
In summary, during a tensile test, near the elastic limit zone, the tensile stress will decrease at a faster rate than the applied load, as the material undergoes plastic deformation and becomes more resistant to further deformation.
