NATURAL FREQUENCIES OF THIN COMPOSITE PLATES SUBJECTED TO STATIC LOADS

Natural Frequencies of Thin Rectangular Plates with Partial Intermediate Supports

−− In the present study, a methodology to find natural frequencies with arbitrary precision of thin rectangular plates on linear intermediate supports and mixed boundary conditions is presented. This means that the edges are total or partially supported, clamped or free, or any combination of these. The layout, number and place of linear intermediate supports are arbitrary, which allows for the...

Buckling Behavior of Long Anisotropic Plates Subjected to Combined Loads

Failure mechanisms in composite panels subjected to underwater impulsive loads

This work examines the performance of composite panels when subjected to underwater impulsive loads. The scaled fluid–structure experimental methodology developed by Espinosa and co-workers was employed. Failure modes, damage mechanisms and their distributions were identified and quantified for composite monolithic and sandwich panels subjected to typical blast loadings. The temporal evolutions...

Collapse Study of a Pair Thin-Walled Prismatic Column Subjected to Oblique Loads

Fatigue Life Assessment of Composite Airplane Wing Subjected to Variable Mechanical and Thermal Loads

The purpose of this paper is to estimate the fatigue life of an airplane wing with laminated composite skin, subjected to variable mechanical and thermal loads. To achieve this aim,at first, the three-dimensional model of airplane wing was drawn in CATIA software. Then, by transferring the model to the ABAQUS software, the finite element model of the wing wascreated. H...
