These videotapes give a comprehensive course of study that presents modern and effective finite element procedures for the linear analysis of solids and structures.

Finite element analysis is the ideal tool for solving the static and dynamic problems encountered in structural designs. Linear analysis -the subject of this course - assumes linear elastic behavior and infinitesimally small displacements and strains.

To establish appropriate models for analysis, it is necessary to become familiar with the finite element methods available. This video course teaches the basic principles used for effective finite element analysis, describes the general assumptions, and discusses the implementation of finite element-linear analysis.

Machinery Noise and Diagnostics examines the excitation, response, and radiation of sound by structures, and the methods of processing noise and vibration data for purposes of noise identification and diagnostics.

In this interesting video course you will explore the development of vibration in a machine by fluctuating forces due to impacts and other interface forces such as gears, cams, and linkages. You will study fluid flow, combustion, and electromagnetic effects and learn how vibration is transmitted through a structure by flexure, torsion, and compression.

New ways of measuring sound radiation are introduced and related to a complete discussion of the geometric and material parameters that determine a machine's capacity to couple with the surrounding air as it vibrates.

You will learn about sensor location and how to reverse the effects of sound propagation with filters. The theory and applications of inverse filters for diagnostic purposes are covered in great detail.

Laboratory, studio, and field demonstrations are a major component of this series, illustrating measurement methods and equipment, properties of structural vibration, and elementary forms of data analysis.

This instructional video course analyzes problems related to the fabrication of welding of large-scale structures and shows specifically how to minimize residual stresses and distortion in structural members.

The high demand for more complex yet lighter welded structures is increasing the technological construction problems and cost of welding large fabrications. Designers are calling for lighter metals and specifying thinner plates for aircraft, autos, buildings, oil rigs, pressure vessels, ships, space vehicles, and similar structures. To effectively design and fabricate highly reliable welded structures, at reduced costs, it is essential that designers specify the correct materials, utilize the proper welding equipment and procedures, have access to good workmanship, and implement strict quality control.

Welded structures are superior to riveted structures, castings, and forgings; however, serious problems do occur. Most are due to local heating by the welding heat source, resulting in complex transient thermal stresses and residual stresses that remain after welding is completed. Distortions also remain, causing cracking and joint mismatch. The results can be premature failures and reduction of buckling strength of some structural members.
