I've made a calibration of the concrete smeared cracking model in abaqus cae 6.10-1 on the basis of an uniaxial tension test.
the specimen is a rectangular solid (pic attached), meshed with C3D8R elements. I applied a pressure (tension) at the face surface.
I declared elastic properties (young's module and poisson's ratio) and the concrete smeared cracking values (comp stress /plastic strain via equivalent stress/strain relation and the tension stiffening values via equivalent strain softening relation)
the tensile strength is 1.905 N/mm2. after calculation the max. stress (2.16 N/mm2) exceeds the tensile strength. how could that be?
the uniaxial compression test works fine.
