Global asymptotic approximations for wrinkling of polar orthotropic annular plates in tension

摘要: The role of polar orthotropy is investigated in relation to an elastic wrinkling problem for annular thin plates tension. An appealing feature this generalised constitutive framework the possibility allowing radial and circumferential directions have different bending stiffnesses. By suitably rescaling buckling equation, three main parameters are identified as being responsible behaviour linear mechanism. We conduct a number singular-perturbation analyses order capture dependence critical loads mode numbers on various physical that enter description problem.
