Kształtowanie płaskich ustrojów nośnych o największej sztywności

A method for geometric shaping of planar beam structure for arbitrary boundary conditions has been described. The finite element method has been used and the elastic potentials of elements which were a measure of objective function have been defined. Beam shaping with respect to maximum stiffness with invariable structure volume has beeb carried out. Wasiutynski's criterion of the comparative elastic potential has been used. By elimination of elements of small thickness a profile of beam structure can by obtained.
