| Abstract: | The longitudinal compressive buckling of long and thin-walled cylinders in yield region is analyzed with the incremental and
finite forms of the endochronic constitutive equation, respectively. The relations between the critical stressσ
cτ
versus the ratio of R (the radius) versus h (the thickness of the wall) are derived. The critical stress of the thin-walled
cylinders made of aluminum alloys AMГ and δ1T are analyzed and compared with the experimental data and the analytical results
based on traditional theory of plasticity. It is seen that, except that theσ
cτ
of the cylinders made of δ1T predicted by the finite form of the endochronic theory seems a little more conservative than
that by traditional deformation theory of plasticity, in most cases, both forms of the endochronic consitutive equation provide
more satisfactory results. |
