Paper Abstract

Few mature techniqes to estimate the damage mechanics of cement mortar are available. A new method of damage evolution prediction and model of cement mortar based on acoustic emission is given. The depict damage evolution of cement mortar, rate process analysis and acoustic emission signal amplitude versus hits correlation figure analysis are propose. THe results show the two methods can predict effectively its damage evolution and damage degree. Based on the experimental results, damage factors were defined as the variation value of acoustic emision energy, and the equation of damage evolution and the constitutive equations presented by acoustic emission parameters are derived. The evolution equation can be used to make dynamic assessment and estimation of damage degrees, which is useful for the study of th quantitative measurement structural damage factors.
