This is mainly because finite element modelling has only been used within the research domain.
Nowadays numerical methods for variable-order fractional differential equations, which mainly cover finite difference methods [18 26], spectral methods [27 29], matrix methods [30, 31], reproducing kernel methods [32, 33], and so on, have been studied extensively by many researchers.
Previously reported 3D designs relied mainly on finite element analyses (FEA) as a guide, but the massive numerical simulations and computational efforts necessary to obtain the assembly parameters for a targeted 3D geometry prevent rapid exploration of engineering options.
While existing parallel methods have been employed mainly for finite element analysis, the present work deals with the entire parallel process of analysis and topology optimization using a parallel processing technique.
Consequently, wideband excitation signal whose energy is distributed mainly in finite frequency points with large frequency spacing is ideal for BIS measurements.
The modelling methods of strip plastic deformation include slab method, variation method, difference method, strip element method, and finite element method, while the modelling methods of rolls elastic deformation mainly include influence function method and finite element method.
Investigations mainly show that the time-varying bearing stiffness fluctuates sinusoidally due to finite number of balls and unbalanced force.
In recent years, the numerical methods for the biharmonic eigenvalue problems adopted mainly the conforming finite element method (see [6 9]), the nonconforming finite element method (see [3, 10 12]), and the mixed finite element method (see [13 16]).
