High Velocity Shock Testing, Equipment and Methods

Description: The need for special high velocity shock testing is pointed out and equipment that has been developed to meet these needs is discussed. The concept of velocity-change and its importance in shock-testing technology is brought out. The three types of equipment discussed are: accelerated drop testers, pneumatic actuators, and air guns. Examples of each type and their capabilities and limitations are presented.

A Method for Performing a Human-Factors Reliability Analysis

Description: Foreword: There has been relatively little work reported on deriving quantitative estimates of the degradation to a man-machine system resulting from human errors. One approach, used in the Reliability Department of Sandia Corporation, is presented here as an example of how such estimating can be done.

Air-Gun Studies of Ferroelectric Materials (Second Printing)

Description: Specimens of two ferroelectric materials, barium titanate and lead-zirconate titanate, have been subjected to high dynamic stresses by impacting them with a projectile accelerated by an air gun. The purpose of these tests was to supplement information previously obtained using high explosives to stress the ferromagnetic materials.

Neutron Flux and Spectra Measurements in the Sandia Pulsed Reactor Facility (SPRF)

Description: Introduction: Neutron measurements were made in the pulsed reactor building and on the safety screen of the pulsed reactor in order to determine the neutron yield of the reactor as a function of (1) distance from the reactor centerline, (2) direction in the reactor building, and (3) position on the reactor safety screen.

SOLSTOR Description and User's Guide

Description: Abstract: This report describes the computer simulation code SOLSTOR. The code simulates energy systems in which electricity is generated by either a photovoltaic (PV) system or a wind turbine generator (WTG). Storage may or may not be present. Backup electricity, if needed, is provided either from a utility grid or from a fuel-burning generator. SOLSTOR minimizes the life cycle cost of providing energy by choosing the optimal solar or wind system component sizes. Rates for electricity purchase… more

Phantom Gage Dimensioning (Combined Part/Gage specifications)

Description: Abstract: This memorandum discusses a new design definition technique, requiring no standard, which pictorially shows part and gage limits on the same drawing. When functional gages, test fixtures, or optical chart gages are the selected inspection method, design, manufacturing process, and gage engineers can use these drawings directly to replace the usual standards-based drawings. In essence, this advanced technology visually describes true position dimensioning and tolerancing. It enables pr… more

A Small-scale Investigation of the Possibility of Constructing Low-Relief Earth-Fill Dams Using Nuclear Explosives

Description: The experiment described herein has shown that the concept of low dams produced by ballistic collision of ejecta from simultaneous detonation of properly spaced parallel rows of charges is a feasible one. Rows of 8-pound charges were buried 3 feet deep with 4-foot spacing between charges. When two such rows of charges were placed parallel and 17.5 feet apart, the maximum height of the "dam" was achieved. The spacing of 17.5 feet between rows corresponds to 4.7 times the crater radius of one 8-p… more
