11、l testing to determine a variety of properties that are subject to ASTM standards.As these stand-ards are used in practical applications,issues with existing and new sensors specif ed in the standards need to be resolved.T e 4th Symposium on the Evaluation of Existing and New Sensor Technologies is
12、intended to provide a forum to disseminate state-of-the-art advances in sensor tech-nology,as well as to identify the limitations of existing sensor technology as it applies to fatigue,fracture,and mechanical testing.T is symposium is the fourth in a series of symposia addressing issues with existin
13、g sensors and development in new sensor technologies for fatigue,fracture,and mechanical testing.In the last decade,digital image correlation(DIC)has been seen as a rapidly growing noncontact strain-measuring technique and has been used extensively in many applications.T e f rst four papers ref ect
14、this trend.Bruhis et al.demonstrate how to use DIC to measure mechanical properties of f llet arc T-welded aluminum alloy AA7xxx extrusions.Kang and Gong show the use of DIC to determine frac-ture behavior of AA6060 aluminum alloy extrusion in specimens with a wide range of stress triaxiality.Willia
15、ms et al.present an application of DIC in assessing yield and forming limit criteria for sheet material deformation and forming.T e f nal paper in this section by Barhli et al.reviews recent work on the analysis of 2D and 3D damage in engineering materials,and describes developments in quantitative
16、analysis of defects by 2D and 3D image correlation.T e next three papers address new developments in potential drop techniques for crack-length monitoring in fracture-toughness testing.Tarnowski et al.present an experimental investigation that quantif es the apparent crack extension,purely as a result of plasticity,in the absence of physical crack growth in a variety of speci-men geometries when using potential drop techniques.Chen et al.show results of applying direct current potential drop tec
