Hierarchical Design and Characterization Lab
Research in the Hierarchical Design And Characterization (HiDAC) lab at Purdue University is broadly concerned with computational and experimental solid mechanics as well as CAD with applications to characterizing failure of microelectronic components and assemblies. The specific focus within these areas is on isogeometric analysis, multi-physics modeling of moving interfaces and boundaries including fracture propagation, shape and topological optimal design as well as in thermal conduction in particulate composites.
