In the present paper, an analytical approach is used to study the thermal deflections of a simply supported composite plate with a beam-like stiffener. The results for a plate–beam system exposed to a sinusoidal thermal load is used to study the effects of the low Earth orbit (LEO) thermal conditions on the composite plates, which have been used in the structure of satellites and spacecraft. To...

The buckling mechanism of diagonally stiffened plates under the combined action shear, bending, and compression is a complex phenomenon that difficult to describe with simple clear explicit expressions. Predicting elastic coefficient accurately crucial for calculating load these plates. Several factors influence plates, including plate’s aspect ratio, stiffener’s flexural torsional rigidity, in...
