Large DIC Experimenters: Use EikoTwin Visual to simulate DIC experimental scenarios and quickly obtain suitable equipment setup solutions!

When conducting DIC tests, optimizing calibration while adapting to the testing environment (mainly industrial environments) can be quite complex. In this case, being able to predict the appropriate position of the camera to ensure good measurements will be very beneficial, as it can avoid repeated testing due to unavailable images and prevent long periods of unavailability of the testing machine when setting up the instruments, effectively shortening the DIC experimental cycle and saving experimental costs.

EikoTwin VisualPrinciple of simulating DIC experimental scenarios

• Create a complete experimental scenario based on the experimental environment and the grid model of the test structure;
• Make moderate adjustments to the texture characteristics of the test object and the lighting conditions of the experiment based on the real situation of the experiment;
• Export images and environmental setup configuration schemes suitable for real experiments;

During DIC experiments, preparation work is very important and is a key factor affecting the success of the experiment, especially when performing DIC measurements on complex structures.

When conducting simulated DIC tests, optimizations and confirmations need to be made in the following areas:

• Confirm that the areas of interest for measurement are within the visible range, which requires the number of cameras;
• The position of the cameras relative to each other and to the parts and their environment;
• The speckle pattern for the intended application must be adjusted, such as size and shape;
• During the experiment, it is essential to ensure uniform lighting in both time and space;
• Confirm whether it is necessary to use a calibration plate in the expected experimental environment.
