    • Damage Precursor Identification in Composite Laminates using Data Driven Approach 

      Elenchezhian, Muthu Ram Prabhu; Vadlamudi, Vamsee; Raihan, Rassel; Reifsnider, Kenneth (American Institute of Aeronautics and Astronautics (AIAA), 2019-01-07)
      **Please note that the full text is embargoed** ABSTRACT: Composite materials are rapidly being used in commercial aviation and other day to day applications. The individual damage modes in composites are very well understood ...

    • Detection and Prediction of Defects in Composite Materials Using Di-Electric Characterization and Neural Networks 

      Elenchezhian, Muthu Ram Prabhu; Nandini, Aishwarya; Vadlamudi, Vamsee; Raihan, Rassel; Reifsnider, Kenneth (Society for the Advancement of Material and Process Engineering (SAMPE)Institute for Predictive Performance and Methodologies, The University of Texas at Arlington Research Institute (UTARI), University of Texas at Arlington, May 2018)
      The state of art non-destructive inspection techniques for composite materials detect the presence of defects in the composite material, but they do not identify what type of defect it is, and hence, further visual inspection ...

    • Dielectric Property Investigation of Degraded Pre-Preg and Performance Prediction of the Final Composite Part 

      Nandini, Aishwarya; Shute, Nina; Elenchezhian, Muthu Ram Prabhu; Vadlamudi, Vamsee; Raihan, Rassel; Reifsnider, Kenneth (Society of the Advancement of Material and Process Engineering (SAMPE)University of Texas at Arlington Research Institute (UTARI), University of Texas at Arlington, May 2018)
      In recent years, fiber-reinforced (i.e., Glass, Carbon, Kevlar) epoxy composites are used widely in structural applications ranging from military and civil aircraft production to recreational consumer products. Most of the ...

    • Predicting Adhesive Bond Performance Based on Initial Dielectric Properties 

      Banerjee, Priyanshu Kumar; Elenchezhian, Muthu Ram Prabhu; Vadlamudi, Vamsee; Raihan, Rassel; Reifsnider, Kenneth (American Society for CompositesDEStech Publications, Inc.University of Texas at Arlington Research Institute (UTARI), University of Texas at Arlington, 2017-10)
      This paper will focus on an approach to study the mechanical as well as the dielectric properties of an adhesive bond. The dielectric testing is done by using Broadband Dielectric Spectroscopy (BbDS), wherein the dielectric ...

    • Quality Assessment of Adhesive Bond Based On Dielectric Properties 

      Elenchezhian, Muthu Ram Prabhu; Vadlamudi, Vamsee; Banerjee, Priyanshu Kumar; Dave, Chaitanya; Mahmood, Anik; Raihan, Rassel; Reifsnider, Kenneth (Society of the Advancement of Material and Process Engineering (SAMPE)University of Texas at Arlington Research Institute (UTARI), University of Texas at Arlington, 2017)
      Composite materials are widely used in Aerospace, Marine and Automotive structures to reduce weight and increase performance. Adhesive bonding improves the stress distribution between the composite materials / dissimilar ...
