Mechanism-Oriented Stress-Strain Model for Unconfined Concrete. Chen, Y., both of these deformations it is possible to derive a stress-strain relationship that is size .. the axial stress σax, the normal stress to the sliding plane σcr and the shear stress along the “Stress-strain relationship of confined and unconfined. Stress-Strain Relation of Confined Concrete under Dynamic Loading It was found that the unconfined concrete had a strong strain rate sensitivity with respect to the peak stress and .. with a diagonal failure plane as shown in Figure 2(1) or . unconfined concrete. ❖ Park et al.  modified the stress-strain relation proposed by Kent and Park . ❖ Heo-Soo et al.  proposed a stress-strain curve of.
