Research

Dr. Walter's research activities are centered around the mechanics of materials. He is particularly interested in using advanced experimental and numerical techniques to investigate the initiation and propagation of damage on micro to macro size scales. Current projects include the study of interfaces in ceramic matrix composites and thermomechanical response of thermal barrier coatings. Dr. Walter's laboratory employs acoustic emission, strain gaging, in situ microscopy, thermal wave imaging, digital image correlation, laser interferometry, and indentation techniques. Dr. Walter is interested in the application of mechanics to better understand surface and interface phenomena in advanced materials, bio materials, and processing methods.
