Static response of thermally loaded sandwich beams with confined horizontal displacements of faces at the supports

Pozorska J., Pozorski Z.

Journal of Applied Mathematics and Computational Mechanics

2014

Vol. 13, nr 2

119--126

The paper examines the problem of the influence of restrictions on freedom of horizontal displacements in thermally loaded sandwich beams. The classical theory of sandwich beams and panels with thin facings and a soft core has been applied. It was assumed that the cross-section of the beam could be asymmetric geometrically and materially. The beam has vertical supports and additional horizontal supports limiting the freedom of horizontal displacements. The supports are linearly elastic and the rigidity of the upper and lower support can be arbitrary. The static problem of single-span beam with support conditions identical at both ends of the beam was solved in the paper. Each of the sandwich facings has been subjected to temperature change. The derived formulas were used in the example illustrating the importance of the problem.

The influence of thermal actions and complex support conditions on the mechanical state of sandwich structure

Błaszczuk J., Pozorski Z.

Journal of Applied Mathematics and Computational Mechanics

2013

Vol. 12, nr 4

13--21

The paper concerns the problem of the influence of thermal actions on the structural behavior of sandwich panels with unspecified elastic supports. An ordinary sandwich panel theory is used. The boundary conditions have the arbitrary form of elastic supports. The solution of a statically undetermined system with limitations of horizontal displacement and rotation is derived. The illustrative examples are presented and the problem solution is discussed.
