Applications of Non-Contact Digital Image Correlation Method (DIC) – A Review

The non-contact digital image of the correlation method on thermal strains has been studied to know the capability of measuring the variations in strains occurring in the alloy surface. By digital image correlation method, we can confirm the strains by heating and cooling of the alloy due to temperatures of sunlight, etc. The techniques are developed and implemented in thermal heating strains are considered through the Noncontact digital image of correlation method. The material can expand or be compressed depending on time variation, temperature changes, and strains generated. There can be a thermal shock which means a sudden change resulting in high variations so to control the results we are doing a study. There are different types of correlation methods which are a naturalistic method, survey method, and archival method in our research we are developing the noncontact analysis which can compare the strains that occurred before and after loads occurred by temperature. The results show the easiest method of analyzing different aspects
