The broad aim of our research is to develop theoretical and computational methods combined with experiments for the assessment, design, optimization and manufacturing of novel materials and structures in various applications. In particular, we are interested in modeling and simulation of additive manufacturing processes, hierarchical materials, multifunctional composites, and image-based (CT, MRI) multiscale modeling of biological materials.
Additively manufactured materials
Modeling temperature and residual stress fields during additive manufacturing (AM) process
Modeling fracture of AM polymers printed at 45°/-45° raster angles with various inter-filament bonding strengths.
Soft materials, flexible and deployable structures
Hierarchical materials and lightweight structures
