The reliable measurement of displacement and strain in materials testing is essential since it characterizes the true mechanical properties of a material. Digital Image Correlation (DIC) is one of the most accurate & versatile, full-field measurement techniques for experimental solid mechanic testing. The technology utilizes cameras of any resolution and frame rate to accurately measure quasi-static, dynamic, and fatigue testing events for literally any materials science & testing application.
Whether measuring strain for; axial, biaxial, fracture, fatigue, pressure, thermal mechanic, compression, bending, shearing, and Forming Limit Curve (FLC) testing, DIC can always be used provided the test surface is visible to at least one camera. Large-scale testing of multiple m2 can be completed using a multicamera setup of up to 16 cameras, alternatively, micro-scale testing of specimens down to mm2 in size can also be measured using a stereoscopic microscope or telecentric (macro zoom) lens configuration.
