The paper discusses the experimental and finite element investigation into the failure mechanisms of uniply graphite-epoxy composite plates with circular holes loaded in uniaxial compression. The effect of hole size on the failure mode is established. Test specimens composed of a single layer of uniply graphite-epoxy sandwiched between two layers of transparent polyetherimide plastic were desig...

Abstract Thermal buckling study on the symmetric laminated composite trapezoidal plate with a circular cutout subjected to uniform increase in temperature for various boundary conditions is explored this paper. In mathematical model, first-order shear deformation principle employed accordance variational energy system. For acquiring thermal temperature, nine-node heterosis relation has been use...

Trapezoidal laminated plates with cutouts are commonly found in many engineering field, especially aerospace structures. In cases these subjected to various harsh environmental conditions during its service life. Thermally induced load is the one which seriously affect buckling characteristics of structural components. The study presents effect rise temperature on thermal trapezoidal composite ...

This paper proposes an explicit method for topology optimization of stiffened plate structures. The present work is devoted to simultaneously optimizing stiffeners’ shape, size and layout by seeking the optimal geometry parameters a series moving morphable components (MMC). stiffeners with straight skeletons curved are considered enhance modeling capability current approach. All represented und...

Aerospace and aircraft companies follow a pyramidal structure of testing, ranging from specimen tests to full-scale tests, for structural design. At the base level, open hole strength evaluation is one qualification procedures composite components. The holes are made in components accommodate bolts rivets order assemble parts into single unit. Holes component also used fulfill functional requir...
