Computer Model for Wave Propagation in Concrete.
Abstract
The main objective of this study was to develop a computer model capable of predicting wave propagation through solids exhibiting random properties and to demonstrate the applicability of the model to structural members made of concrete. The model was developed, and a numerical example was prepared for a concrete control cylinder subjected to an impact load. The modulus of elasticity and the density of the concrete cylinder were assumed to be correlated homogeneous random functions of the axial coordinate. The randomness of the material properties was introduced as a multivariate stochastic process. Realizations were digitally generated for the properties of the concrete control cylinder. The solution for the displacement and stress response was obtained for each realization utilizing the finite element method. Sample statistics for quantities of interest were determined by means of a Monte Carlo simulation. (Author)
