Free vibrations of linear viscoelastic polymer cantilever beams

open access: yesComptes Rendus. Mécanique, 2020
The free vibrations of cantilever slender beams of polymers, which are viscoelastic materials, are theoretically described using the simple Euler–Bernoulli assumption.

Free vibrations of non-uniform CNT/fiber/polymer nanocomposite beams

open access: yesCurved and Layered Structures, 2017
In this paper, free vibrations of non-uniform multi-scale nanocomposite beams reinforced by carbon nanotubes (CNTs) are studied. Mori-Tanaka (MT) technique is employed to estimate the effective mechanical properties of three-phase CNT/fiber/polymer ...

Free vibration analysis of functionally graded rectangular nanoplates considering spatial variation of the nonlocal parameter

open access: yesArchives of Mechanics, 2017
We present a new nonlocal elasticity-based analysis method for free vibrations of functionally graded rectangular nanoplates. The introduced method allows taking into account spatial variation of the nonlocal parameter.

Low Frequency Sloshing Analysis of Cylindrical Containers with Flat and Conical Baffles

open access: yesInternational Journal of Applied Mechanics and Engineering, 2017
This paper presents an analysis of low-frequency liquid vibrations in rigid partially filled containers with baffles. The liquid is supposed to be an ideal and incompressible one and its flow is irrotational.

Shape Optimization of a Column Modelling the Bridge Span under a Specific Load - Numerical and Experimental Studies

open access: yesCommunications, 2023
This work is dedicated to the problem of optimizing the shape of columns modelling bridge span subjected to the selected specific load case. Based on Hamilton's principle, motion equations and boundary conditions were defined.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

open access: yesMolecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.
