Evaluation of global load sharing and shear-lag models to describe mechanical behavior in partially lacerated tendons

The mechanical effect of a partial thickness tear or laceration of a tendon is analytically modeled under various assumptions and results are compared with previous experimental data from porcine flexor tendons. Among several fibril-level models considered, a shear-lag model that incorporates fibril...
