The residual strains of five kinds of steel fiber concrete in each loading and unloading cycle are decreased as the steel fiber content are increased in the whole test process.
The characteristics of different concrete materials and the influence of content of steel fiber on the failure criterion have been considered in the general failure criterion.

并且讨论了网格细化、钢纤维嵌入长度、体积含量、基体强度、纤维刚度等参数变化对计算模型产生的影响。
And discussed the influence which caused by thin grid, the insert length of steel fiber, volume ratio, substrate intensity, fiber rigidity and so on.
