The impact of science on society by James Burke( Book )

3 editions published in 1985 in English and held by 513 WorldCat member libraries worldwide

The impact of science on society is examined in this publication's coverage of a series of public lectures that commemorated the 25th anniversary of the National Aeronautics and Space Administration. Edited versions of four speeches are presented which address the impact of science on society from the time of humanity's first significant scientific invention to that of expected future scientific advances. The papers include: (1) "The Legacy of Science" by British historian James Burke; (2) "Accomplishments of Science by the Year 2000" by television science editor and reporter Jules Bergman; (3) "Our Future in the Cosmos--Computers" by scientist and science fiction writer Dr. Isaac Asimov; and (4) "Our Future in the Cosmos--Space" also by Dr. Isaac Asimov. Audience questions and lecturer responses follow each of the papers. Biographical sketches of each presenter are also included. (Ml)

Improved equivalent linearization implementations using nonlinear stiffness evaluation by Stephen A Rizzi( )

5 editions published in 2001 in English and held by 352 WorldCat member libraries worldwide

This report documents two new implementations of equivalent linearization for solving geometrically nonlinear random vibration problems of complicated structures. The implementations are given the acronym ELSTEP, for "Equivalent Linearization using a Stiffness Evaluation Procedure." Both implementations of ELSTEP are fundamentally the same in that they use a novel nonlinear stiffness evaluation procedure to numerically compute otherwise inaccessible nonlinear stiffness terms from commercial finite element programs. The commercial finite element program MSC/NASTRAN (NASTRAN) was chosen as the core of ELSTEP. The FORTRAN implementation calculates the nonlinear stiffness terms and performs the equivalent linearization analysis outside of NASTRAN

Thermomechanical response of shape memory alloy hybrid composites by Travis L Turner( )

3 editions published in 2001 in English and held by 347 WorldCat member libraries worldwide

This study examines the use of embedded shape memory alloy (SMA)actuators for adaptive control of the themomechanical response of composite structures. Control of static and dynamic responses are demonstrated including thermal buckling, thermal post-buckling, vibration, sonic fatigue, and acoustic transmission. A thermomechanical model is presented for analyzing such shape memory alloy hybrid composite (SMAHC) structures exposed to thermal and mechanical loads. Also presented are (1) fabrication procedures for SMAHC specimens, (2) characterization of the constituent materials for model quantification, (3) development of the test apparatus for conducting static and dynamic experiments on specimens with and without SMA, (4) discussion of the experimental results, and (5) validation of the analytical and numerical tools developed in the study. The constitutive model developed to describe the mechanics of a SMAHC lamina captures the material nonlinearity with temperature of the SMA and matrix material if necessary. It is in a form that is amenable to commercial finite element (FE) code implementation. The model is valid for constrained, restrained, or free recovery configurations with appropriate measurements of fundamental engineering properties. This constitutive model is used along with classical lamination theory and the FE method to formulate the equations of motion for panel-type structures subjected to steady-state thermal and dynamic mechanical loads. Mechanical loads that are considered include acoustic pressure, inertial (base acceleration), and concentrated forces. Four solution types are developed from the governing equations including thermal buckling, thermal post-buckling, dynamic response, and acoustic transmission/radiation. These solution procedures are compared with closed-form and/or other known solutions to benchmark the numerical tools developed in this study. Practical solutions for overcoming fabrication issues and obtaining repeatable specimens are demonstrated
