摘要：The article presents an analysis of geometrically nonlinear contact tasks for the system of plates. The peculiarities of the presented tasks consist in research of a pressure-deformed state of two plates connected with a bolt fixture with a clearance and loaded with a uniformly distributed transverse force along the upper edge. Both geometrical and structural non-linearities are presented in the study tasks. The geometrically nonlinear formulation determines the SSS for plates connected with a bolt fixture with a clearance. Maximum deformation of such plates is 0.028 m and the equivalent (von-Mises) stress is 1200 MPa. The bolt skewing and the plate deformation increase tensile forces in the bolt, thereby increasing the force of the bolt fixture tightening (1500 N to 4000 N). The proposed methodology can be used for solving similar tasks as it considers a wide range of operating loads. In case when the researched object is a solid plate, geometrically linear and non-linear formulations do not guarantee reliable results.
