Objective. The article proposes a method for finite element analysis of pipe-concrete columns in physically nonlinear setting by reducing three-dimensional problem to twodimensional one based on the hypothesis plane sections. Method. equations theory plasticity concrete G.A. Geniev are used. technique was tested comparing solution with calculation LIRA-SAPR software package, as well experimenta...

An approximate numerical mthod is presented for analysis and determination of modal characteristics in straight, pretwisted non-unifom helicopter blades. The analysis considers the coupled flapwise bending (out of plane), chordwise bending (in plane), and torsion vibration of both rotating and non-rotating blades. The proposed method is based on the integral expansion of Green functions (struct...

This paper presents a perspective on figures in plane geometry by means of which various theorems can be systematically proved. The theorem on which this perspective is based, described in Section 2.3, has a particularly useful corollary concerning the matching of angles subtended by vertices. The approach shares some of the objectives of Wu’s method ([10] and [11]) for automation in plane geom...

The analysis of rotational effect on the characteristics of plane waves propagating in a half space of generalized thermo-piezoelectric medium is presented in context of linear theory of thermo-piezoelectricity including Coriolis and centrifugal forces. The governing equations for a rotating generalized thermo-piezoelectric medium are formulated and solved for plane wave solutions to show the p...

Performance analysis and experimental verification of a coherent free-space optical communications receiver in the presence of simulated atmospheric turbulence is presented. Bit-error rate (BER) performance of ideal coherent detection is analyzed in Section II, and the laboratory equipment and experimental setup used to carry out these experiments are described. The key components include two l...
