A method for calculating curved composite elements with a constant bending radius on elastic shear bonds is presented, which is a refinement of the classical theory of calculation of composite rods by A. R. Rzhanitsyn in relation to such rods. The compliance of connections is taken into account only in the tangential direction-along the tangent to the points in the joints between the connected layers. The connections in the radial direction are assumed to be absolutely rigid, which is true when the predominant share of vertical loads is applied to the upper layer, causing it to be pressed against the lower layer, since in this case the function of transverse connections will be performed by the contacting surfaces of the layers. The force method is used to solve the problem.The main unknown is the distribution function of the total shear forces along the tangents to the points along the joints connecting the layers. An example of calculating the strength and vertical displacements of a curved composite element composed of two layers is provided. An analysis has been made to determine the influence of factors such as shear bond stiffness, radius of curvature, and the presence of thrust on the stress-strain state of an element.
