Abstract In this paper, we propose a general method for solving structural mechanics problems by developing “functional model”. It is implemented defining the required geometrical and physical relationships in their form via analytical numerical functions. For that purpose, special programming language Calcpad used. The obtained data structure processed core engine, which generates computer cod...

In this paper, a numerical experimental study about coupled vibration and natural frequency of thin-walled beams with an arbitrary closed cross-section is presented. A new beam dynamic transfer matrix method, named TDTMM, presented in the domain for beam, which expands advantages general method (GDTMM). The theory takes into account influence warping effect, that is, both bimoment B rate twist ...

Recently, we evaluated the virtual cross-section for Bhabha scattering in pure QED, up to corrections of order α 4 (N F = 1). This calculation is valid for arbitrary values of the squared center of mass energy s and momentum transfer t; the electron and positron mass m was considered a finite, non vanishing quantity. In the present work, we supplement the previous calculation by considering the...
