High Order Integration of Smooth Dynamical Systems: Theory and Numerical Experiments
This paper describes a new class of algorithms for integrating linear second order equations, and those containing smooth nonlinearities. The algorithms are based on a combination of ideas from standard Newmark integration ...
Almost Poisson Integration of Rigid Body Systems
In this paper we discuss the numerical integration of Lie-Poisson Systems using the mid-point rule. Since such systems result from the reduction of hamiltonian systems with symmetry by Lie Group actions, we also present ...
Structural Optimization in a Distributed Computing Environment
This report presents the formulation and testing of a Feasible Sequential Quadratic Programming (FSQP-DIS) optimization algorithm customized to a Distributed Numerical Computing environment (DNC). DNC utilizes networking ...
Solid Modeling of Reinforced Concrete Beams, Part I: Data Structures and Algorithms, Part II: Computational Environment
This 2-part paper describes a solid modeling methodology for the interactive design and analysis of reinforced concrete (RC) beam structures. Part I covers the data structure and algorithms for steel reinforcing bar ...
XBUILD: Pre-processor for Finite Element Analysis of Steel Bridge Structures
Historically, the lack of interactive pre-processors to describe tedious finite element models has hindered the use of the finite element method for bridge analysis. The work performed in the present study mitigates this ...
Pre-Processor for Finite Element Analysis of Highway Bridges
Historically, the lack of interactive pre-processors to setup tedious finite element problem descriptions has hindered the use of the finite element method for bridge analysis. The work performed in the present study ...
