An incomplete generalized variational functional for naturally curved and twisted composite box beams with complete constrained boundaries at two ends is established by means of Lagrange multiplier method. The equations of motion governing the dynamic behavior of the beams and corresponding boundary conditions are derived from the stationary condition of the functional. The non-classical influences...
This paper presents an analytical method for the study of naturally curved and twisted beams under complicated loads, with special attention devoted to the solving process of governing equations which take into account the effects of torsion-related warping as well as transverse shear deformations. The solutions derived in this paper can be used for the analysis of the beams, including the calculation...
