Differential
Quadrature
Methods
The original direct differential quadrature (DQ) method has been known to fail for
problems with strong nonlinearity and material discontinuity as well as for problems
involving singularity, irregularity, and multiple scales. But now researchers in applied
mathematics, computational mechanics, and engineering have developed a range of
innovative DQ-based methods to overcome these shortcomings. Advanced Differential
Quadrature Methods explores new DQ methods and uses these methods to solve
problems beyond the capabilities of the direct DQ method.
After a basic introduction to the direct DQ method, the book presents a number of
DQ methods, including complex DQ, triangular DQ. multi-scale DQ. variable order DQ.
multi-domain DQ, and localized DQ. It also provides a mathematical compendium that
summarizes Gauss elimination, the Runge-Kutta method, complex analysis, and more.
The final chapter contains three codes written in the FORTRAN language, enabling
readers to quickly acquire hands-on experience with DQ methods.
Focusing on leading-edge DQ methods, this book helps readers understand the
majority of journal papers on the subject. In addition to gaining insight into the dynamic
changes that have recently occurred in the field, readers will quickly master the use of
DQ methods to solve complex problems.
Features
•
Discusses the limitations of direct DQ methods and common strategies to remove
these limitations
•
Presents formulations of several new DQ methods
•
Applies novel DQ methods to solve problems that are beyond the capabilities of
the direct DQ method
•
Includes results that represent the latest important developments of DQ methods
•
Provides FORTRAN code for readers to quickly acquire hands-on experience with
DQ methods
