Abstract
This paper constitutes a first attempt to explore the influence of porosity on bending static analysis of functionally graded (FG) beams using a refined mixed finite element beam model. The material properties of functionally graded porous beams are estimated using a modified power law distribution with two different types of porosity namely even and uneven distributions. The potential of the proposed model is highlighted via a comparison study. Then, a parametric study is carried out to show the effects of power law index, porosity coefficient, boundary conditions and types of porosity distributions on deflections and stresses of the studied FG beams.
