The construction, automotive, and aerospace industries all make extensive use of short fiber-reinforced thermoplastic composites because of its remarkable mechanical qualities, lightweight nature, and ability to be recycled. However, anisotropic effects from injection molding, like fiber orientation and weld lines, make it difficult to anticipate their structural performance, especially under buckling stresses. To account for manufacturing-induced anisotropy in finite element calculations, this study offers an integrated computational framework that combines Moldex3D, Digimat RP, and ABAQUS. The framework assesses the buckling and nonlinear anisotropic behavior of hollow square cross-section columns made of Polyamide 6 reinforced with 40% glass fiber (PA6-GF40). J2 plasticity models the behavior of the elastoplastic matrix, whereas the Mori-Tanaka technique forecasts effective material properties. The findings provide a solid methodology for creating highperformance composite structures under challenging loading circumstances, emphasizing the important influence of fiber orientation and weld lines on structural stability.
