| 要旨 | A non-local plasticity model is used to investigate the effect and applicability of using different forms of gradient parameter on localization phenomena and on fracture energy consumed. It was found that the form of gradient influence factor significantly influences the formation of localization band and the consumption of fracture energy. Based on the results an approximate analytical expression is proposed to calculate the fracture energy when the gradient term is chosen independently. Finally some experimental results are simulated to show how the values of different material parameters can be selected. |
