ADDRESSING STRAIN MEASUREMENT REQUIREMENTS FOR INDUSTRY AND RESEARCH
Applications: ASAME Target Model for 2D Measurements
Use One System for 3D and 2D Measurements

The ASAME Target Model can be used for two types of measurement work.
[1] Measurement of out-of-plane strains and the corresponding geometry over the surface of a part after deformation.
[2] Measurement of in-plane strains and corresponding 2D geometry points over the surface of a flat part during deformation (i.e. tensile testing). With the Nikon D300s digital camera, images can be captured at a rate of up to 7 frames per second (fps). Some sample measurement results of real-time in-plane surface strains are given in the clip below.
Research with ASAME and GPA
An updated list of citations for published technical papers that note the use of ASAME and/or GPA systems is available at our site. Some topics of recent work include experimental verification of FEA models, tailor-welded tube hydroforming, Erichsen testing of welded joints, and the effects of movable dies in hydroforming.
