摘要
实验研究表明,钢纤维砼在受力变形时伴有微损伤的发展,损伤演化一方面伴随着材料的流变而发展,另一方面又受应变率的影响。因此,可用钢纤维砼的率型损伤演化律来说明材料的损伤破坏现象。
The experiments show that the mechanical behavior of steel fiber reinforced concrete (SFRC) is a microdamage development process under loading. The damage evolution is affected by the deformation and strainrate. A ratedependent damage evolution law of SFRC is given to describe the damage and failure of the concrete.
