Coefficient of the intensity of static indefinability and achievement of absolute plasticity's condition
Limit condition of round and ring plates from разносопротивляющихся materials is considered on the basis of a condition P. Balandin's plasticity. Are used entered and described piecewise and linear approximations of an ellipse of tension of Balangding and on them to basis for the generalized characteristics (the moments and speeds кривизн) laws of axisymmetric deformation round and ring are received plates at an axisymmetric cross bend.
