Washington Center for X-ray and Imaging Technology (WACXIT)

Department of Civil and Environmental Engineering

Mission

The Washington State High-Resolution X-ray Computed Tomography Laboratory (WACXIT) at Washington State University promotes the advanced characterization, simulation and design of solids including granular soils, metals, ceramics, plastics, wood, geological and biomaterials. WACXIT actively collaborates on research and teaching with local as well as international academic institutions and industries. WACXIT also promotes scientists, faculty and student exchanges.

Research

The major thrust of the research activities at the WACXIT is the characterization and modeling of microstructure and defects in solids and structures. The three dimensional topology of defects (such as cracks and voids) and microstructure (such as grains and particles) in materials can be reconstructed via computed tomography and understood in terms of undamental characteristics. Current studies include development of improved advanced theoretical models for the prediction of deformation, fatigue, strain localization, liquefaction and fracture processes in materials. Current research activities include :

  • Microstructural investigation of unsaturated granular geomaterials
  • Quantifying the Fabric Tensor
  • Fiber distribution in fiber reinforced concrete
  • Damage Detection and Life Analysis of Composites
  • Damage Detection in Rapidly Solidified Materials
  • Bifurcation and Instabilities in Geomaterials
  • Powder Metallurgy and Materials Fabrication for Petroleum Industry
  • Modeling Grain Shape Anisotropy in Multi-Phase Alloys
  • Evaluations of Remodeling of Canellous born and evaluation and design of blended polymer
  • Granular Dilatancy
  • Modeling of Grain Boundaries in Crystalline Material
  • Deformation and Damage in irradiated Materials
  • Localization and damage in metals under cyclic fatigue

Educational Outreach

The WACXIT promotes distant learning and active research through the uses the internet for meetings and for carrying out "long distance" real time experiments in which researchers conduct the experiments, collect and process data from their own computer terminals.
