SUMMARY:Polar Interpolants for Thin-Shell Microstructure Homogenization
DESCRIPTION:Technical Papers\n\nAntoine Chan-Lock (Universidad Rey Juan Ca
 rlos) and Miguel A. Otaduy (Universidad Rey Juan Carlos, Facebook Reality 
 Labs)\n\nThis paper introduces a new formulation for material homogenizati
 on of thin-shell microstructures. It addresses important challenges that l
 imit the quality of previous approaches: methods that fit the energy respo
 nse neglect visual impact, methods that fit the stress response are not co
 nservative, and all of them are limited to a low-dimensional interplay bet
 ween deformation modes. The new formulation is rooted on the following des
 ign principles: the material energy functions are conservative by definiti
 on, they are formulated on the high-dimensional membrane and bending domai
 n to capture the complex interplay of the different deformation modes, the
  material function domain is maximally aligned with the training data, and
  the material parameters and the optimization are formulated on stress ins
 tead of energy for better correlation with visual impact. The key novelty 
 of our formulation is a new type of high-order RBF interpolant for polar c
 oordinates, which allows us to fulfill all the design principles. We desig
 n a material function using this novel interpolant, as well as an overall 
 homogenization workflow. Our results demonstrate very accurate fitting of 
 diverse microstructure behaviors, both quantitatively and qualitatively su
 perior to previous work.\n\nRegistration Category: Full Access, Full Acces
