A STABILITY CRITERION OF AN ORTHOTROPIC BI-MATERIAL NOTCH BASED ON THE STRAIN ENERGY DENSITY
Hrstka M., Profant T., Klusák J., Ševeček O., Kotoul M.
pages 261 - 264, full text

A bi-material notch 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 -integral method. Knowledge of the basic stress concentrator characteristics such as stress singularity exponent and corresponding regular and auxiliary eigenvectors allows the Ψ-integral 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.
