Abstract

Many parts of spacecraft, airplanes are made up of aluminum, due to its property of less density, which is deep in sections. For the analysis of deep parts of any structure, a shear deformation theory using the trigonometric sinusoidal function in displacement field in terms of thickness coordinate is developed to obtain the shear deformation effects. The shear stresses are obtained from the use of constitutive equations with outstanding accuracy, satisfying the zero shear stress at the both, top and bottom of beams. Also, the theory not requires the shear correction factor. By using the principle of virtual work, the governing differential equations and boundary conditions are obtained. A deep aluminum beam is assumed subjected to a cosine load for the analytical study to show the accuracy of the theory. The results are compared with other theories.
