Path Dependency in Thermoelastic Stress Analysis

Experimental Mechanics, 2004
In this paper we review the basis of the technique for thermoelastic stress analysis and, in particular, we examine the relationship between the theory and the technique in common practice. The theory of thermoelastic stress analysis is based on the thermomechanical behavior of bodies, which takes strain and temperature as state variables that are path-

Introduction to thermoelastic stress analysis

Strain, 1999
AbstractThe theory of thermoelastic stress analysis is reviewed and the assumptions in developing the theory are assessed. The equipment for thermoelastic stress analysis is based on infrared detection systems. The commercially available systems are described and appraised. Techniques for calibrating the output from the detectors are also provided.

Industrial Applications of Thermoelastic Stress Analysis

Applied Mechanics and Materials, 2004
The advent of new thermoelastic stress analysis (TSA) technology has widened the industrial applications of the technique. Three case studies where data have been taken in previously inaccessible or unfeasible cases are presented. The case studies, taken from both the aerospace and automotive industries, will demonstrate the novelty of these ...

Thermoelastic Stress Analysis of Vascular Devices

Strain, 2007
Abstract:  The feasibility of using thermoelastic stress analysis (TSA) to characterise angioplasty balloons and Nitinol self‐expanding stents was investigated. A detailed description of the experimental apparatus developed is provided. A review of recent studies by the authors describes calibration procedures for the balloon and the stent materials ...

The effects of motion on thermoelastic stress analysis

Composite Structures, 1991
Abstract An indepth examination of the effects of specimen motion on the technique of thermoelastic stress analysis is presented. It is shown that the presence of a non-uniform temperature distribution, coupled with the material motion due to cyclic loading, can greatly corrupt the measured data.

Applications and potential of thermoelastic stress analysis

Journal of Materials Processing Technology, 1997
Abstract Stress changes in an elastic solid are accompanied by small temperature changes which are directly related to the stress change. This phenomenon (referred to as the “thermoelastic effect”) is the basis of the thermoelastic stress analysis technique which is now in use in many industrial organisations and research centres in Europe, Australia,

Thermoelastic-Plastic Stress Analysis

1986
The significant shift in design requirements in recent years for high performance and efficient components in the aerospace and nuclear industries has made sophisticated design analysis a necessity. In addition to the desired high performance, the structural integrity of the machine components has become a prime concern of designers as well as of the ...

THERMOELASTICITY: The use of thermoelastic stress analysis to identify defects in polymeric materials

Insight - Non-Destructive Testing and Condition Monitoring, 2004
The work described here emerged from an EPSRC-funded programme investigating the thermomechanical ageing of selected engineering plastics used in the offshore oil & gas industry. The polymers investigated are PEEK and PEK, materials of the polyaryletherketone family.

Thermoelastic Stress Analysis of the Human Tibia

1997
The thermoelastic stress analysis method is a non-contact technique which utilizes the thermoelastic qualities of hard tissues such as bones. It enables easy measurement and imaging of surface stress distributions. Using this approach, we performed stress analyses of human tibias in simulated loading conditions at various modes of varus valgus loading ...

Thermoelastic stress analysis for linear thermoelastic bodies

2007
The thermoelastic stress analysis for linear thermoelastic bodies is developed as a mathematical support to the infra-red radiometric method applied to structures under cyclic loading conditions. The author considers the relation between the temperature variation and the stress variation and takes into account the dependence of the Poisson and Young ...
