An alternative version of constructing limit surfaces for anisotropic solids

This paper deals with constructing closed everywhere smooth surfaces in 6D space of symmetric second-rank tensors by means of a conoidal anisotropic transformation of the unit sphere S⁵. A special case of such transformations is proposed and the surface convexity conditions are pointed out. These surfaces can be utilized in the strength and plasticity theories of isotropic and anisotropic solids.Published in Mekhanika Kompozitnykh Materialov, Vol. 31, No. 4, pp. 488–493, July–August, 1995.
