Abstract: The creation of an efficient automated capability for minimum weight design of structures is reported. The ACCESS 1 computer program combines finite element analysis techniques and mathematical programming algorithms using an innovative collection of approximation concepts. Design variable linking, constraint deletion techniques and approximate analysis methods are used to generate a sequence of small explicit mathematical programming problems which retain the essential features of the design problem. Organization of the finite element analysis is carefully matched to the design optimization task. The efficiency of the ACCESS 1 program is demonstrated by giving results for several example problems.

TL;DR: This report describes computer program NOYFB: a method of determining the static configuration of sub-surface oceanographic moorings for the purposes of system design and analysis of performance.
Abstract: This report describes computer program NOYFB: a method of determining the static configuration of sub-surface oceanographic moorings for the purposes of system design and analysis of performance. Operating instructions and the program listing are included as appendices. The program is written in Fortran II specifically for W.H.O.I. Hewlett-Packard 2100 series shipboard computer systems. The user acts as the computer operator in a decision-making capacity, specifying, evaluating, and modifying the mooring composition and control and environmental parameters. Principle features of the program are: a) useable both at sea and ashore, b) real time selection of output formats and devices, c) standard W.H.O.I. mooring component characteristics are stored in the program with the option of user modif ication, d) capable of handling complex, non-uniform current prof iles , e) automatic component length adjustment for depth cri tical instruments, f) calculation of launch transients and reserve buoyancy, g) the ability to imput/output the mooring composition and characteristics from/to punched paper tape.

TL;DR: In this article, NASTRAN contains two techniques to solve the differential stiffness problems, one is incorporated in a new static analysis rigid format and the other is contained in a normal modes analysis rigid formats.
Abstract: NASTRAN contains two techniques to solve the differential stiffness problems. One is incorporated in a new static analysis rigid format and the other is contained in a new normal modes analysis rigid format. The two techniques relative to computational accuracy and time of execution are compared.
