摘要：

In this paper, fused deposition modeling (FDM) parts are characterized for flexural behavior using an experimental and numerical investigation. Flexural test was conducted using ASTM D790 standard to find the flexural strength and modulus. Tensile test and compression test were conducted using ASTM D638 and ASTM D695, respectively, to evaluate the mechanical properties. Finite element (FE) model using classical laminate theory was developed by considering a few build parameters of FDM. Flexural test condition was simulated using the elastic properties obtained from experiments based on CLT approach with orthotropic and isotropicmaterialmodel. The results showed that the computational model built using classical laminate theory was well correlated with the experiments as compared to that of isotropic model for the same loading condition.
