This paper proposes a model and a mechanism for explaining the mechanical behavior of extruded powder aluminum at elevated temperature. This behavior is significantly different from that of ingot-cast and drawn aluminum which is subjected to the same

Visioplastic analysis is used to compare strain fields produced in cylindrical aluminum billets extruded at elevated temperature through axially symmetric dies that have either a cosine or a conical profile. The visioplastic method consists of comput

The system described in this paper is intended to study the gait of individuals by placing minimal interference on the normal walking motion. It is intended to be portable and easy to use by nonmedical technicians. The results obtained here show prom

Photoelastic data are combined with the finite-element method for stress solutions over regions partially bounded by free surfaces and axes of symmetry. Least-squares solutions are obtained without presumed values of applied forces at element nodes a

Statistical methods are described to evaluate data quality. Quality is considered to consist of close grouping for several readings of the same variable; or consistency of measurements. Statistical methods include histograms, construction of Gaussian

Least-squares is described as a method for solving problems where there is an excess of information available. This is often the case in experimental mechanics. The method can be used to include information from different sources; experimental and th

Piecewise approximation functions are compared to single functions which are defined over entire sets of data. The former are presented as providing close fits to the data and as being desirable for performance of subsequent calculations. The cubic s

The purpose of this chapter is to study the frequency content of data recorded as a function of time and which includes repetitive events. It will be shown that such data can be considered as being composed of a number of sinusoidal functions and an
