A Strain Rate-Dependent Damage Evolution Model for Concrete Based on Experimental Results by Peng Wan, Xiaoyan Lei, Bin Xu, Hui Song

“…In this paper, a strain rate-sensitive isotropic damage model for plain concrete is proposed to describe its nonlinear behavior. Cyclic uniaxial compression tests were conducted on concrete samples at three strain rates of 10−3s−1, 10−4s−1, and 10−5s−1, respectively, and ultrasonic wave measurements were made at specified strain values during the loading progress. …”
