Strength evaluation of adhesive joint with thermal stress using ultrasonic signal processing method

열응력이 발생하는 접착이음부에서의 초음파 신호처리기법을 이용한 강도평가

One approach to testing the suitability of an adhesive joint for a particular application is to build and test to destruct ion a representative sample of the joint. The nondestructive test will not measure strength directly but will measure a parameter which can be correlated to strength. It is therefore, essential that a suitable nondestructive test is chosen and that its results are correctly interpreted. In this paper, typical defects found in adhesive joints are described together with their significance. The limits and likely success of current physical nondestructive tests are described, and future trends outlined.
