Sažetak
Knowledge about material inner behaviour during loading has always been of interest in mechanical sciences. Several methods such as strain gauge measuring, photoelasticity, digital image correlation, etc. have been develop through the years with goal of determining stress and strain distribution of loaded body. Although strain gauges are appropriate approach when acquiring strain of dynamically loaded structure, they are providing just point wise information about the strain distribution. Digital image correlation (DIC) is providing information about dynamically loaded structures up to certain velocities, depending on photographic performances, optics, and sensitivity of digital cameras (CMOS or CCD sensor based). In our previous [1] work we have shown similarity of infrared image patterns and effective strain distribution obtained by DIC. When using thermography. It was shown that infrared thermography based on InSb focal point array detector operating on cryogenic temperatures can be used for higher loading velocities where DIC is not providing results. Also infrared thermography cannot be used for lower loading velocities as thermal effect is dissolved due to cooling of unloaded material. Here we present an approach can be used to relate these individual measurements with the motivation of using only one of the two cameras while doing field work.
