Abstract

Our paper deals with theoretical and numerical study of the discrete fully stress design (FSD) algorithms for thin shell finite elements. Authors present seven mathematical formulations of the direct strength designing. Relations between stresses, membrane and bending element forces (moments) and element thicknesses are studied. Using selected numerical tests of the proposed algorithms are compared.

Keywords:
