Abstract
Bimaterial interface cracks in composite materials can either continue propagating along the interface or deviate their path, an event known as crack kinking, which can heavily impact structural integrity. To understand the crack kinking phenomenon, in literature is proposed a linear mathematical model based on six coefficients, which depend only on the kink angle and material properties. While earlier studies offer limited data on these coefficients for specific bimaterials, our work presents a verified semi-analytical approach that served as the foundation for the newly developed Matlab app introduced to compute coefficients for a wider range of bimaterial combinations.
