Dorota Pawlus
2008 Lecture Notes in Computer Science  
The annular plates with three-layered, cross-section structure having the soft core in the range of critical behaviour after loss of static and dynamic stability have been analysed.  ...  Several meshes of plate models, which can be applied in numerical calculations have been presented.  ...  Problem Formulation The problem undertaken in this paper consists in the evaluation of the influence of the model structure of the three-layered plate on the computational results.  ...

2017 FME Transaction  
The shear strength characterization of bonded joints involving adherends with a remarkably different stiffness has a peculiar interest in industrial applications.  ...  This work proposes and investigates three innovative specimens (an axisymmetric annular, a tensile and a torsional one) purposely developed to manage dissimilar adherends bonded with adhesive in thin film  ...  These three layers are bonded each other. The plates (A) act as connecting elements between the top and bottom cross-head of the testing machine, and the sandwich specimen.  ...

Pushing the Limits of the Multi-modal Equivalent Circuit Approach for Stacks of 2-D Aperture Arrays [article]

Antonio Alex-Amor, Francisco Mesa, Ángel Palomares-Caballero, Carlos Molero, Pablo Padilla
2020 arXiv   pre-print
Many frequency selective surface (FSS) structures are based on the use of a single periodic array of slot/apertures in a conducting sheet embedded in a layered medium.  ...  A key feature of the formulation is that linear transformations between the apertures of adjacent plates (rotation, translation, and scaling) can be dealt with from a purely analytical perspective.  ...  This is a remarkable feature, since the performance of glide-symmetric structures can rarely be described with circuit models due to the strong interaction between adjacent layers.  ...
