Stress Wave Scattering in Concrete: An Investigation Through Simple Finite Element Models

This study presents a method to estimate the scattering component of stress wave attenuation in concrete and concretelike materials through the use of simple finite element models in two dimensions. The method employs a correction to account for losses due to normal radiation pattern effects and test setup geometry. Among the test samples for which results appear are models of various thicknesses and models with differing inclusion parameters such as spatial distribution, concentration, size, and shape; the tests employ a range of input frequencies. Tested spatial distributions include both periodic and aperiodic arrangements of inclusions.
