Disappearance conditions of thermal stress singularities based on stress intensity in two and three-phase bonded structures

摘要: The characteristics of stress singularities near the free edge interface bonded dissimilar materials subjected to change in temperature are investigated. thermal stresses represented by sum singular terms types r-1 and log r, no ones particular ones. functions, K × F (j=1,2,3), associated with except contributing described as new intensity factors. is obtained from technique Mellin transform calculated numerical analysis such finite element analysis. emphasis here placed on clarifying material combinations arbitrary wedge angles elastic properties yielding = 0. results can be used determine material/geometry which ensures that residual will compressive.
