Originální abstrakt

A bi-material notch or a crack terminating at the bi-material interface composed of two orthotropic materials is considered. The stress and displacement fields are expressed using the Lekhnitskii-Eshelby-Stroh formalism for plane elasticity and as the result of an application of the psi-integral method. Knowledge of the basic stress concentrator characteristics such as stress singularity exponent and corresponding regular and auxiliary eigenvectors allows the psi-integral method allows one to evaluate the generalized stress intensity factor of the studied stress concentrator. The achieved results are used for the next analysis such as assessment of the potential direction of the crack initiation and for notch stability criteria assessment as an extension of standard crack fracture mechanics.
