چکیده
The paper investigates the results of solving spatial contact problems on free support bending rods (hereinafter referred to as beams) elastic quarter-space and octant space. objectives study include determining stress state pads, obtaining a picture distribution stresses over them, studying features that arise when these problems. main solution method is B. N. Zhemochkin, based discretization areas by replacing continuous with point one. This approach allows us reduce problem calculation statically indeterminate system using well-developed methods structural mechanics. mathematical model be solved built assumption linear (geometric physical linearity) work both element foundation. Since in process deformation end sections beam can break away from areas, belong group previously unknown area. design schemes such are constructively nonlinear, their carried out iterative methods. Based considered problems, it has been found geometrically symmetrical left right quarter-spaces (space octants) equal but different mechanical characteristics, well loading, values reactions, considering them resultants coordinates points application not each other. leads similar result case resting one side, edge space In addition, constant torque appears along entire length element, indicating torsional transverse condition.
