Biography

ZHANG Yancheng is a researcher specializing in the numerical modeling of additive manufacturing processes, with significant expertise in thermomechanics, multiscale simulation, and materials behavior. His work focuses on the analysis of processes such as *Laser Powder Bed Fusion* (L-PBF) for metals, such as nickel-based superalloys (Inconel 718), and semi-crystalline polymers, notably polyamide-12 (PA12). His research aims to understand the complex physical mechanisms involved in manufacturing, such as thermal interactions, phase transformations, residual stresses, and deformations, by incorporating innovative approaches such as *Cellular Automaton* (CA) methods, crystalline plasticity, and *Reduced Order Modeling* (ROM). ZHANG Yancheng has also contributed to the development of numerical frameworks that couple thermomechanics, hydrodynamics, and crystallization kinetics, enabling predictive simulation of defects and the mechanical properties of manufactured parts. His recent work explores the optimization of hybrid processes (*Metal Hybrid Additive Manufacturing*) and the improvement of dimensional accuracy, while seeking to reduce computational costs through adaptive meshing or multiscale modeling strategies.
