Abstract
The invention relates to the technical field of building materials, in particular to a softening curve model suitable for UHPC, which is established by using an inverse analysis method, describes the characteristics of a softening curve and the characteristics of UHPC fracture, integrates load-crack opening displacement data (namely a P-CMOD whole process curve) of a self three-point bending test, inverts the softening curve of UHPC by using experimental data, and provides a soft curve model suitable for UHPC. According to the softening curve model suitable for the UHPC and established by using the inverse analysis method, the softening curve with innovativeness and uniqueness is established by adopting the inverse analysis method and combining the physical significance of the UHPC, and the softening curve model can be widely and universally used for showing the physical significance of fiber concrete in the fracture process.
