| 摘 要： | 钢纤维聚合物混凝土(SFPC)是由聚合物混凝土(PC)基体参入适量钢纤维形成的纤维增强复合材料，其抗单轴抗压强度明显高于聚合物混凝土的单轴抗压强度。本文用宏观热力学理论，处理材料损伤问题，基于损伤力学原理推导出SPPC单轴抗压应力-应变关系模型，该模型对进一步拓宽钢纤维聚合物混凝土(SFPC)在国民经济中的应用领域具有一定的指导作用。

| Abstract: | Steel fiber polymer concrete(SFPC)is a kind of steel fiber polymer composite that is made of polymer concrete(PC) and steel fiber weighted in propriety amount.The compressive Strength of SFPC is higher than that of polymer concrete obviously. This paper deal with damage mechanism of SFPC by macro thermodynamics and deduce the uniaxial compressive stress-strain model of SFPC on the basis of damage mechanics principle. This model will play a role in expanding the field where SFPC is used in national economy. |
