Advanced beam theories for the analysis of beam structures [PDF]
, 2021 Η παρούσα διδακτορική διατριβή αποτελεί συμβολή στην ανάπτυξη εξελιγμένων θεωριών δοκού για την ανάλυση ραβδωτών φορέων. Οι εξελιγμένες θεωρίες δοκού που αναπτύχθηκαν λαμβάνουν υπόψη φαινόμενα γενικευμένης στρέβλωσης (διατμητική υστέρηση λόγω κάμψης και στρέψης), διαστρέβλωσης (παραμόρφωση διατομής – distortion), ενώ πραγματοποιείται και γεωμετρικά μη ...

Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Finite Element Coding of Functionally Graded Beams under Various Boundary and Loading Conditions
Journal of Applied Research on Industrial Engineering, 2017 Detailed formulation and coding of exact finite element is carried out to study the static behavior of a layered beam structure. The beam element is modelled based on the first-order shear deformation theory and it is assumed to be composed of three ...

Towards linear modal analysis for an L-shaped beam: equations of motion [PDF]
, 2013 We consider an L-shaped beam structure and derive all the equations of motion considering also the rotary inertia terms. We show that the equations are decoupled in two motions, namely the in-plane bending and out-of-plane bending with torsion.

Poincaré Bessel beams: structure and propagation [PDF]
Journal of Optics, 2019 Non-separable superpositions of polarization and spatial modes in Gaussian beams have shown rich patterns of spatially-variable polarization encoded in the transverse mode of the light, with the potential for many applications. In this work we investigate encoding similar types of superpositions in Bessel beams.
