Topology Optimization: A Compact Review and Comparation on Level Set Technique Development in Single and Multi-material

Lightweight structural design is being researched and applied across many fields, including mechanical engineering, aerospace, and manufacturing. Among the many methods used to reduce material weight while ensuring structural strength, topology optimization has become a common choice due to its ability to optimize sing...

Direct FE2 multiscale modeling of transverse matrix cracking in thermoplastic composites using stochastic representative volume elements

Fiber-reinforced thermoplastic composites are critical in aerospace for their lightweight and durable properties. However, predicting transverse matrix cracking remains challenging due to microstructural heterogeneity and the stochastic nature of fiber arrangements. This study introduces a stochastic Direct FE 2 fr...

Numerical investigation of transverse bridging development in mode I delamination of fiber-reinforced composite laminates

Transverse fiber bridging is an extrinsic toughening mechanism in cross-ply composite laminates, but its numerical representation remains challenging because it involves coupled transverse cracking and interlaminar delamination. This study develops a cohesive-zone-based finite element model to investigate the apparen...
