要旨 Numerical simulation of concrete fracture process requires a rational formulation of the localized phenomenon keeping the continuity of strain between the localized zone and outside the localized zone. Applicability of gradient plasticity models to capture localization has already been established 1), 2). In this study a one dimensional gradient plasticity model is used to investigate the effect of some parameters on the overall load-deflection response and on localization phenomenon. Also some numerically obtained results are compared with experiments that shows the model's applicability in mode-1 type fracture. It has been shown that one-dimensional formulation is useful to verify test results and to select proper values of model parameters.
