It is proposed to use the method of finite elements to calculate the strength of ship structures. The structure is broken down into a definite number of structural finite elements that interact with each other at a limited number of contact nodal points. Writing out the equilibrium conditions for these points, the authors obtain the necessary linear algebraic equations to determine the main unknowns displacement components of the nodal points. Using the unknowns that have been found, the stress state is then determined in each of the elements and, consequently, in the structure as a whole.
