A Finite Element Model to Study the Effect of Porosity Location on the Elastic Modulus of a Cantilever Beam

The effect of the location of porosity concentration on elastic modulus of a cantilever beam is investigated. First, two-dimensional investigation with beam theory, Euler-Bernoulli and Timoshenko, was performed to estimate the modulus based on load-deflection curve. Second, three-dimensional finite element model (FEM) in Abaqus was developed to identify the effect of porosity concentration. The use of macro-models such as beam theory and three-dimensional FEM enabled enhanced understanding of the effect of porosity on modulus.
