The lumped model parameters approach for static and dynamic power-law beam problems

Begzhigitov, Madi (Nazarbayev University School of Science and Technology, 2019-04-29)

It is important to estimate the natural frequencies of the structural elements in the design of mechanical or electromechanical structures. There is a wide use of single lumped-parameter spring-mass models in the industry ...
Nonlinear Waves in Rods and Beams of Power-Law Materials

Wei, Dongming; Skrzypacz, Piotr; Yu, Xijun (Journal of Applied Mathematics, 2017-07-13)

Some novel traveling waves and special solutions to the 1D nonlinear dynamic equations of rod and beam of power-law materials are found in closed forms. The traveling solutions represent waves of high elevation that ...
On the solvability of the Brinkman-forchheimer-extended darcy Equation

Skrzypacz, Piotr; Wei, Dongming (arXiv.org, 2016)

The nonlinear Brinkman-Forchheimer-extended Darcy equation is used to model some porous medium ow in chemical reactors of packed bed type. The results concerning the existence and uniqueness of a weak solution are ...
