Non-Linear Rheological Model of Concrete
In the paper a new nonlinear rheological model of concrete for structures subjected to long term processes, especially those including the imposed strains /shrinkage, thermal strains etc./, is presented. The constitutive relations in incremental forms are shown for various cases of the plane state of stresses. Results of calculations of two tests for concrete bars subjected to the trial for compression and imposed strains, enforcing tensile stresses, are presented.
