TL;DR: In this article, a model of an inextensible elastic rod with equal principal stiffnesses is presented, which permits large deflections and finite rotations and accounts for tension variation along its length.
Abstract: A new three-dimensional finite element model of an inextensible elastic rod with equal principal stiffnesses is presented. The model permits large deflections and finite rotations and accounts for tension variation along its length. Its use in static analysis is described and a time integration method for dynamic analysis is developed. Accuracy of the spatial discretization and stability of the time integration method are demonstrated by comparison of numerical results with exact solutions for certain nonlinear problems.

TL;DR: StatMOOR as discussed by the authors is a static mooring analysis program written in BASIC language and is one program in a hierarchy of programs developed at the Naval Civil Engineering Laboratory for moorings analysis.
Abstract: : STATMOOR is a static mooring analysis program written in BASIC language and is one program in a hierarchy of programs developed at the Naval Civil Engineering Laboratory for mooring analysis. STATMOOR analyzes the static response of a single-point moored vessel and hawser. The MENU arrangement of the program lends itself to a user-oriented conversational mode. The user has the option to enter, review, edit input, and obtain calculated results in printed tabular, video tabular, or video graphics form. Steady current, wind, and wave loads are considered. Wind load estimates are considered to be as accurate as the user's knowledge of the wind environment; current and wave loads are in a preliminary form and merit further refinement. STATMOOR was written to demonstrate the utility and ease of use of conversational mode programs and the potential for computer programs to replace bound design manuals. It s unique in that it incorporates recently developed wind load information, can confidently be used with little or no training, and is easily adaptable to most desk top computers. (Author)

TL;DR: PACE incorporates both static analysis and dynamic analysis capabilities and it provides features that enable systematic and comprehensive evaluations of large-scale microcoded systems.
Abstract: This paper describes PACE (Product Assurance Code Evaluation) System, a tool for evaluating microprograms. PACE incorporates both static analysis and dynamic analysis capabilities and it provides features that enable systematic and comprehensive evaluations of large-scale microcoded systems.The PACE static analysis capability performs a control flow analysis of the code being evaluated, reports various anomalous program constructs, and generates a program flow graph that is subsequently employed by PACE's dynamic analysis procedures.The PACE dynamic analysis capability uses encoded execution trace data to produce microcode test-coverage reports and formatted code-execution traces. The dynamic analysis capability provides quantitative code execution coverage data that enables an assessment of testing thoroughness and is useful in the identification of effective regression test cases.
TL;DR: In this paper, a simplified method for seismic analysis of four types of auxiliary mechanical equipment commonly used in nuclear power plants is presented, based on actual dynamic analyses and studies of a large number of equipment items of these four different basic configurations.
Abstract: This paper presents a simplified method for seismic analysis of four types of auxiliary mechanical equipment commonly used in nuclear power plants. This method is based on actual dynamic analyses and studies of a large number of equipment items of these four different basic configurations. For this equipment, it is shown that a static analysis, using the spectral acceleration at the first frequency in the case of flexible components, and maximum absolute floor acceleration in the case of rigid components, provides realistic and valid response results. Consequently, more complex analysis or static analysis with acceleration coefficients greater than unity, which has been typically required, is not necessary for this type of equipment.
TL;DR: In this article, the dynamic and static analysis methods used to model the nonlinear structural behavior of the Shuttle Orbiter's tile/pad thermal protection system are discussed. But, the analysis of the analysis to square tiles subject to sinusoidal and random excitation is presented along with appropriate test data.
Abstract: The dynamic and static analysis methods used to model the nonlinear structural behavior of the Shuttle Orbiter's tile/pad thermal protection system are discussed. The structural evaluation of the tile/pad system is complicated by the nonlinear stiffening, hysteresis and viscosity exhibited by the pad material. Application of the analysis to square tiles subject to sinusoidal and random excitation is presented along with appropriate test data. Correlation is considered good. In order to treat the stress analysis of thousands of individual tiles, a nonlinear static analysis was developed which utilizes equivalent static loads derived from the dynamic environment. Tensile stress at the bondline is examined in thousands of unique tiles.
