Experimental Stress Analysis

Course Description

An Experimental Analysis Course has the task of presenting the main methods of experimental analysis in the awareness that stress and strain are responsible for a variety of phenomena of structural failures of modern artefacts, which are d ue to se veral causes such as load estimates, insufficient stress analysis and lack of data on materials. The discipline was created as a selection of tools for finding results when analytical solutions did not formerly exist, but today it has the new task of clarifying the limitations of analytical theories, of validating numerical results, of building the fundaments of phenomenological theories and simulations and of allowing reliability and life extension estimations especially in case of incomplete data and badly posed problems. 

Course Objective

The course covers the basic aspects of experimental stress analysis that includes exhaustive treatment of the most versatile techniques like photoelasticity and strain gauges and also a brief introduction to the emerging techniques like digital image correlation. In addition it also provides the fundamental aspects of six different experimental techniques such as Moiré, Brittle Coatings, Holography, Speckle Methods, Thermoelastic Stress Analysis and Caustics.
