When it comes to the structural material in terms of both lightweight and strong materials, porous beam has emerged as a promising option. Porous materials, known for being light weight, have applications in aerospace, automotive and biomedical engineering, where light weighted yet strong material are crucial. The current research is focused on the nonlinear behavior of porous beam due to difference in loading and beam geometry. Here, a finite element models (modeled using FEM software) are used to analyze how the beam deforms, under different load patterns. In current study, the research aims to offer insights into how to model porous structural member for better performance in engineering works. The study focuses on the factors like different sizes of porosity, different boundary conditions, different loading types, and their impact on the bending behavior of the porous beam. The result reveal that porosity significantly effects performance and show that these beams can be customized to use less material while retailing important structural qualities. This study fills the gaps in chosen field of research work and provide stage for creative engineering solutions focusing on the structure’s effective stability.
