Stress intensity coefficient analysis of isotropic binary material under thermal stress

This thesis study was carried out on eleven samples of binary material consisting of araldite and steel. Firstly, impact tests were performed on the materials and dynamic parameters (ω, ξ, x) of the material were obtained. Secondly, stresses were found by applying loads on the material at three different temperatures (28° C, 35° C and 50° C). Then the samples of the numerical analysis program MARC modeled and frequency values of the first three modes of the material under thermal stress were obtained. KI and KII stress intensity coefficient were also found using the necessary equations. As a result, numerical analysis results were compared with results obtained from static and dynamic experiments.
