An Efficient Reduced-Order Approach for Nonaffine and Nonlinear Partial Differential Equations
(2007-01)In the presence of nonaffine and highly nonlinear terms in parametrized partial differential equations, the standard Galerkin reduced-order approach is no longer efficient, because the evaluation of these terms involves ... -
Linear Thermodynamics of Rodlike DNA Filtration
(2007-01)Linear thermodynamics transportation theory is employed to study filtration of rodlike DNA molecules. Using the repeated nanoarray consisting of alternate deep and shallow regions, it is demonstrated that the complex ... -
Reduced Basis Approximation and A Posteriori Error Estimation for Stress Intensity Factors: Application to Failure Analysis
(2007-01)This paper reports the development of reduced basis approximations, rigorous a posteriori error bounds, and offline-online computational procedures for the accurate, fast and reliable predictions of stress intensity factors ... -
Reduced Basis Method for 2nd Order Wave Equation: Application to One-Dimensional Seismic Problem
(2007-01)We solve the 2nd order wave equation, hyperbolic and linear in nature, for the pressure distribution of one-dimensional seismic problem with smooth initial pressure and rate of pressure change. The reduced basis method, ... -
Smoothed Finite Element Method
(2007-01)In this paper, the smoothed finite element method (SFEM) is proposed for 2D elastic problems by incorporation of the cell-wise strain smoothing operation into the conventional finite elements. When a constant smoothing ...
