Sažetak
A method for the improvement of the conditionality of the stiffness matrix of a structure in the element analysis is developed, which is based on the reduction of the number of nonzero nondiagonal elements of the stiffness matrix via making the shape functions partly orthogonal. A number of system of optimal shape functions is constructed and the evaluation of efficiency of their employment is carried out for 1 D, 2 D and 3 D finite elements. The proposed sets of shape functions increase the efficiency of application of FEM in metal forming processes.
