Evaluation of polymer viscoelasticity by integrated micro-indentation test with optical flow algorithm

This study aims to directly evaluate the viscoelastic (creep) parameters of polymer materials by integrating a micro-indentation test with an optical flow (OF) algorithm and an embedded center of dilatation (ECD) model. After indentation, the in-plane displacement field on the specimen surface is me...
