Abstract
This paper presents a novel approach for analyzing functionally graded beams with porosity on elastic foundations. A new first-order shear mixed beam element is proposed, incorporating enriched transverse shear stiffness and parabolic stress distributions. The element avoids shear locking and demonstrates high convergence and accuracy. Compared to existing models, the proposed beam element convergence with only one to two elements, so it provides a reliable numerical tool for analyzing both homogeneous and functionally graded beams. The study investigates the influence of elastic foundations and porosity, offering benchmark solutions for future research. The proposed element finds applications in civil, mechanical, and aerospace engineering, enabling efficient analysis and optimization of structural systems under complex loading. It also holds potential for vibration and buckling analysis, enhancing structural design and stability.
