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 ...
A Systems Approach to Nonlinear Finite Element Analysis of Shell Structures
This report describes a systems approach to the nonlinear finite element analysis of shell structures. The research objective is to understand the structure a small language and computational environment should take so ...
Structural Matrix Computations with Units: Data Structures, Algorithms, and Scripting Language Design
Despite the well-known benefits of physical units, matrices,and matrix algebra in engineering computations,most engineering analysis packages are essentially dimensionless.They simply hold the engineer responsible for ...
ALADDIN: A Computational Toolkit for Interactive Engineering Matrix and Finite Element Analysis
This report describes Version 1.0 of ALADDIN, an interaction computational toolkit for the matrix and finite element analysis of engineering systems. The ALADDIN package is designed around a language specification that ...
