A near-infrared camera (NIR) is employed to monitor layer-by-layer in-situ electron beam powder bed fusion (E-PBF). We aim at demonstrating that such a device allows various kinds of flaws be reliably captured thanks qualitative thermal information. Defects as distortions or uneven top surfaces can detected in the NIR-images. Information about temperature heterogeneities also linked with some o...

A bstract framework is presented to extract and understand decision-making information from a deep neural network (DNN) classifier of jet substructure tagging techniques. The general method studied provide expert variables that augment inputs (“eXpert AUGmented” variables, or XAUG variables), then apply layerwise relevance propagation (LRP) networks both with without variables. are concatenated...

Building upon recent works devoted to the development of a stress-based layerwise model for multilayered plates, we explore an alternative finite-element discretization conventional displacement-based method. We rely on mixed approach where both stresses and displacements are interpolated. Since conforming finite-elements ensuring traction continuity difficult construct, consider hybridization ...

In recent years, researchers have been working to interpret the insights of deep neural networks in pursuit overcoming their opaqueness and so-called ‘black-box’ tag. this work, we present a new posthoc visual interpretation technique that finds out discriminative image regions contributing highly towards networks’ prediction. We select most discernible set neurons per laye...

Recent developments on the optimization and parameter estimation in hybrid active-passive composite sandwich structures are presented. For this purpose, a mixed layerwise finite element model has been formulated, by considering a higher order shear deformation theory to represent the displacement field in the viscoelastic core and a first order theory for the displacement fields of the adjacent...

Vibration suppression of smart beams using the piezoelectric patch structure is presented in the present work. The smart system consists of a beam as the host structure and piezoceramic patches as the actuation and sensing elements. An experimental set-up has been developed to obtain the active vibration suppression of smart beam. The set-up consists of a smart cantilever beam, the data acquisi...
