Buckling of composite cylindrical shells with rigid end disks under hydrostatic pressure
A.V. Lopatin,Evgeny V. Morozov +1 more
TL;DR: An analytical solution of the buckling problem formulated for a composite cylindrical shell with its ends closed by rigid disks and subjected to hydrostatic pressure is presented in this article, where the problem is solved using Fourier decomposition and the Galerkin method.

Proof of convergence for a set of admissible functions for the Rayleigh-Ritz analysis of beams and plates and shells of rectangular planform
TL;DR: In this article, the authors present a discussion on the characteristics of sets of admissible functions to be used in the Rayleigh-Ritz method (RRM), including polynomials, trigonometric functions and a combination of both.

Gradient Deficient Curved Beam Element Using the Absolute Nodal Coordinate Formulation
TL;DR: In this paper, a gradient deficient beam element of the absolute nodal coordinate formulation is generalized to a curved beam for the analysis of multibody systems, and the performance of the proposed element is discussed by comparing with the fully parametrized curved beam element and the classical large displacement beam element with incremental solution procedures.

Evaluation of wafer bonded CMUTs with rectangular membranes featuring high fill factor
TL;DR: This paper found that reducing the cell-to-cell spacing could cause bending of the center support post, which amplifies nonuniformities in collapse voltage to 18.4% between neighboring cells, and found that increasing the support post width alleviated the post bending problem.

Mass-Stiffness Change Method for Scaling of Operational Mode Shapes
TL;DR: In this paper, a method is applied for scaling of the operational mode shapes on a basis of both mass and stiffness change of the test structure, which is shown that the advantage of the applied method is that the first modes of the structure are more affected by the stiffness changes and consequently the corresponding scaled mode shapes are more accurate.
