Steady state response due to moving load at the free surface of micropolar cubic crystal

Kumar R., Ailawalia P.

International Journal of Applied Mechanics and Engineering

2007

Vol. 12, no 2

401-411

The steady-state response of a micropolar cubic crystal due to a moving load has been studied. The eigen value approach using the Fourier transform has been employed and the transform has been inverted by using a numerical technique. The displacement and stress components in the physical domain are obtained numerically. The results of displacement and stresses have been compared for the micropolar cubic crystal and a micropolar isotropic solid. The numerical results are illustrated graphically for a particular model.

Interaction due to mechanical sources in micropolar cubic crystal

Kumar R., Ailawalia P.

International Journal of Applied Mechanics and Engineering

2006

Vol. 11, no 2

337-357

The response of a micropolar cubic crystal due to various sources has been investigated. The eigen-value approach after applying Laplace and Fourier transforms has been employed to solve the problem. The integral transforms have been inverted by using a numerical technique to obtain the displacement, microrotation and stress components in the physical domain. The results of normal displacement, normal force stress and tangential couple stress have been compared for a micropolar cubic crystal and micropolar isotropic solid and illustrated graphically.

Elastodynamics of Inclined Loads in a Micropolar Cubic Crystal

Kumar R., Ailawalia P.

Mechanics and Mechanical Engineering

2005

Vol. 9, nr 2

57--75

The analytic expressions for the displacement components, microrotation and stresses at any point in an infinite micropolar cubic crystal as a result of inclined load of arbitrary orientation have been obtained. The inclined load is assumed to be a linear combination of a normal load and a tangential load. The eigenvalue approach using Laplace and Fourier Transforms has been employed and the transforms has been inverted by using a numerical technique. The numerical results are illustrated graphically for a particular material.
