EikoTwin DIC uses digital image correlation (DIC) directly on your simulation's finite element (FE) mesh. This allows for direct comparison of experimental displacement and strain measurements with numerical simulation results, unlike traditional DIC. It helps users quickly improve simulations, saving time and avoiding trial and error by providing immediate insights.
Displacements, strains, and correlation residuals (at pixel scale) are measured directly on the surface of the part.
There is no technical limit to the numbers of cameras, allowing the user to measure displacements and strains all around the FE mesh.
Virtual displacement sensors, extensometers, and strain gauges can be positioned anywhere to compare DIC results, physical sensors, and simulations.
Tests use 2 digital cameras for 3D displacement via stereo-correlation, plus IR/log cameras. This non-contact method maps displacement onto the 3D FE model. Analysis shows 3-step sheet distortion: swells towards laser, then opposite, partially returns upon cooling.
