Theory and Application of Fracture Dynamics in Concrete

Abstract:

Lattice Discrete Particle Model (LDPM) provides accurate representation of concrete behavior under cycling loading both in tension and unconfined, confined, and hydrostatic compression. In this paper, LDPM is used to simulate tensile fracturing as demonstrated by the successful simulation of three points bending tests on notched specimens, the result show that it is able to reproduce pre-peak nonlinearity as well as softening post-peak behavior. It reproduces realistically the development of crack pattern due to tensile stresses and also could predict correctly size effect on specimen load carrying capacity.
