Part I: Investigation of drape variability via 3D scanning}, volume={99}, ISSN={["1754-2340"]}, DOI={10.1080/00405000701489222}, abstractNote={Abstract The objective of this two part paper is to present a method of enhancing accuracy of fabric drape simulation using commercially available software. In Part I, we report results of an investigation of drape variability for a set of fabrics having varied mechanical properties, an essential step in defining accuracy for drape simulation. Results illustrate that fabric drape behaviour is highly variable and thus provide no single drape configuration to target with simulation. Development of a revolutionary method for capturing drape of actual fabrics and measuring that drape in a virtual three-dimensional (3D) environment is also presented. The method allows identical drape measurement processes to be implemented for actual and simulated fabrics and provides opportunity for use of additional measures to assess fabric drape in three dimensions. The accomplishments presented in this paper are utilized to demonstrate, in Part II, development of a relationship that enhances realism of particle model simulations generated using the commercial drape simulation software.}, number={3}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Kenkare, Narahari and Lamar, Traci A.

Part II: Optimized drape simulation using industry-specific software}, volume={99}, ISSN={["1754-2340"]}, DOI={10.1080/00405000701489198}, abstractNote={Abstract Three-dimensional virtual representations of fabrics are done based on mass-spring modeling, which represents cloth as a mesh of particles connected by springs. The spring constant values input to the model correspond to the mechanical properties of the modeled fabric. For apparel, these representations have been incorporated into commercial software packages for use in design and development of garments. However, fabric mechanical property values as derived using industry test methods cannot be input directly into the commercial software to produce simulations that accurately represent a specific fabric. A systematic way of selecting input parameters to a particle model was developed by comparing the drape of circular fabric samples whose mechanical properties were measured by the Kawabata evaluation system to simulations produced by the particle model using methods developed in Part I of this paper. Also, a relationship was developed between measured fabric mechanical properties and simulation input parameters and then tested on simulations of apparel samples.}, number={3}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Pandurangan, Pradeep and Eischen, Jeffrey and Kenkare, Narahari and Lamar, Traci A.

However, effective damage detection in these structures is complicated by a lack of interior access. In this paper, the feasibility of various non-destructive evaluation (NDE) techniques for detecting the presence, location, and magnitude of damage in GRID-LOCK® is investigated. Experiments conducted on a GRID-LOCK® test structure reveal that vibration-based damage detection and optical nde methods are superior to ultrasonic C-scans in detecting disbond defects. Finite-element analysis (FEA) is used to interpret experimental results and highlight the advantages of alternate NDE approaches.}, number={5}, journal={MECHANICAL SYSTEMS AND SIGNAL PROCESSING}, author={Pandurangan, Pradeep and Buckner, Gregory D.}, year={2007}, month={Jul}, pages={2185–2197} } @article{pandurangan_buckner_2007, title={Defect identification in GRID-LOCK (R) joints}, volume={40}, DOI={10.1016/j.ndtient.2006.12.006}, number={5}, journal={NDT & E International}, author={Pandurangan, P. and Buckner, G.
