A new method for calculating volumetric structural elements in the general case of their stress-strain state

The parametric equations of the strength surface in space internal force factors (IFF) are given for 9 forces and moments homogeneous anisotropic bodies. As special cases, similar isotropic bodies that resist tension compression differently (and equally). A variant kinematic method theory limit equilibrium is proposed. rigid-plastic model a deformable solid body used. It assumed massive structural elements destroyed by dividing into parts deform relatively little (“absolutely rigid finite elements”, ARFE) have 6 degrees freedom three-dimensional space. process destruction material goes along infinitely thin generalized surfaces (GDS), on which work all active IFFs taken account. To determine minimum kinematically possible load, simplex linear programming (LP) was
