- Description:
- The paper presents stochastic discrete simulations of concrete fracture behavior. The spacial material randomness of local material properties is introduced into a discrete lattice-particle model via an autocorrelated random field generated by the Karhunen-Loève expansion method. The stochastic discrete model is emploeyd to simulate failure of the three-point-bent beams with and without a central notch.. The effect of spatial randomness on the peak load and energy dissipation is studied. and Obsahuje seznam literatury
