Stress-Strain Relation for Concrete and Constricted Concrete According to Mander [3]
Comparison of the stress-strain relation of concrete and constricted concrete according to Mander [3], displayed in blue and red.
The image compares the stress-strain relation for concrete and constricted concrete according to Mander's theory. The blue curve represents unreinforced concrete, while the red curve represents constricted concrete. This relationship shows the difference in deformation resistance between the two materials. The x-axis represents strain and the y-axis represents stress.
