AbstractAbstract
[en] In this paper constitutive relationships are proposed and the rupture behaviour of kinematically determinate structures are studied for variable loading and isothermal conditions. The theoretical results are used to predict the life of a beam of rectangular cross-section subjected to uniform bending moments. The results of experiments carried out on beams subjected to variable and reverse moments are shown to verify the

AbstractAbstract
[en] In this paper an approximate method is derived which enables a lower bound on the rupture life to be obtained for kinematically determinate structures subjected to variable load and isothermal conditions. The bound on the rupture life is expressed in terms of the energy dissipation rates within the structure corresponding to steady-state creep. The method has the advantage that, for a large number of structures, bounds on the rupture lives can be easily obtained from existing steady-state solutions. The effect of multi-axial stress creep-rupture upon the structural performance is examined and bounds are derived for materials which obey maximum tension and octahedral shear stress criteria. For both multi-axial stress rupture laws and structures subjected to variable and reverse load conditions formulae are derived which express the lower bound rupture life in terms of the behavior of a steady-load uni-axial creep rupture test. The rupture life of the structure can then be determined from the calculated representative rupture stress for the structure and uni-axial deformation and rupture data for the material. The results of experiments which have been carried out on copper and aluminium beams, tested at 250+-1/20C and 210+-1/20C respectively, are presented for variable and reverse load conditions. The copper and aluminium alloys were selected to represent materials which obey maximum tension and octahedral shear stress rupture criteria respectively. For both rupture laws the experimental values of the rupture times are closely predicted by the representative rupture stresses and uni-axial data. Statement are made concerning the rupture of materials under uni-axial compressive stresses

AbstractAbstract
[en] The service life of structures operating under the conditions of variable temperature and loading is limited by excessively large deflections or by a material deterioration referred to as creep rupture. Basing on the Kachanov concept of damage, Leckie and Hayhurst suggested constitutive equations which reasonably represent the macroscopic behaviour of creeping material. This paper shows on the basis of these equations and the analysis of creep mechanisms the possibilities of a description of the creep behaviour of material under variable temperature and loading conditions. Also the influence of cyclic proportional loading and temperature gradient upon the rupture life and strains of a thick cylinder is investigated in detail. (Auth.)
