Pyramidal lattice truss structures with hollow trusses
TL;DR: In this article, a periodic diamond hole pattern sheet consisting of 304L stainless steel hollow tubes was made by an alternating collinear lay-up process followed by vacuum brazing.

Vibration and sound radiation of sandwich beams with honeycomb truss core
TL;DR: In this paper, a finite element model is developed to evaluate the structural and the acoustic behavior of the considered class of sandwich beams, and the model is formulated by employing dynamic shape functions, derived directly from the distributed parameter model of beam elements.

Free flexural vibration analysis of symmetric honeycomb panels
S.D. Yu,William L. Cleghorn +1 more
TL;DR: In this paper, the free flexural vibration of symmetric rectangular honeycomb panels having simple support boundary conditions is investigated using the classical plate theory, Mindlin's improved plate theory and Reddy's third-order plate theory.

Analysis of isotropic and multilayered plates and shells by using a generalized higher-order shear deformation theory
J.L. Mantari,C. Guedes Soares +1 more
TL;DR: In this article, a generalized 5 degrees of freedom (DOF) higher-order shear deformation theory (HSDT) was introduced to study the bending and free vibration of plates and shells, which may be used to create other HSDTs.

A numerical analysis approach for evaluating elastic constants of sandwich structures with various cores
Q.H. Cheng,Heow Pueh Lee,Chun Lu +2 more
TL;DR: In this article, the authors employ finite element analysis (FEA) to derive equivalent stiffness properties of sandwich structures with various types of cores, different from conventional continuum cores and honeycomb core.

Vibration of plates
TL;DR: The fundamental equation of classical plate theory can be found in this article, where anisotropic and variable-thickness versions of the classical plates are considered, as well as other considerations.
A general small-deflection theory for flat sandwich plates
Charles Libove,S. B. Batdorf +1 more
TL;DR: In this article, a small-deflection theory is developed for the elastic behavior of orthotropic flat plates, in which deflections due to shear are taken into account, which covers all types of flat sandwich construction.
