Why does the stress of concrete exceed the yield stress of material properties in tensile analysis of rebar and concrete in abaqus?

The material properties of the rebar and concrete are set to be completely elasto-plastic.
Material properties were set as shown in the following image.
​​​​​​​ However, the yield stress is exceeded at the integration point of concrete. How can I prevent the yield stress from being exceeded? The coefficient of friction is 0.3. Thank you in advance.
