The elastic-plastic bend of circular plates are considered. The metal
alloys have different strength properties under tension and compression. Such
materials are called plastically anisotropic or materials with SD-effect. Investigation of their properties is an important task in the design and construction of
new building structures. We use the properties of SD-materials, the classical Hill’s
theory of plasticity and various mathematical models in which the transversal
isotropy parameter and the plastic anisotropy parameter (SD-parameter) we take
into account. We present asymptotic formulas for stresses that we use for numerical modeling and graphical representation of elastoplastic properties of circular
SD-plates. We obtain the numerical solution of the plate bend after calculating
the system of fifth-order differential equations. We use Euler difference method or
software package COMSOL 5.4. The results of the numerical solution we present
in the form of figures and graphs.
