STRESSED STATE IN THE WALL OF A COMPOSITE BEAM SUBJECT TO LOCAL TORQUE AND LOCAL LOAD
Differential equations of the angle of twist and deplanation as functions of a spatial variable are derived within the framework of the Slywker's semi-shearing theory. An example of an I-shaped cross-section bar loaded with a vertical concentrator force applied with eccentricity yields expressions for the angle of twisting, deplaning and their derivatives. The graphs of the distribution of the above values along the length of the rod are constructed in the presence of an eccentricity of the application of the load, which causes the appearance of local torsion. A technique for determining the magnitude of a bimoment is proposed. Graphically, the change in its magnitude along the length of the beam, depending on the magnitude of the eccentricity, is shown. It was found that, in the presence of the eccentricity of the application of the load, in addition to bending stresses, there would be stresses from local torsion. The value of the bimoment will increase with increasing eccentricity, and its peak values will be below the point of application of the load.
