Abstract

Finite element analysis has been performed to determine the local stress field in a tensile loaded composite specimen with an embedded EFPI-sensor. The sensor/coating and the coating/composite interfaces have been distinguished as the sites where failure is initiated due to stress concentrations caused by the cavity in the EFPI-sensor. An increase in the strength of the interfaces is an important task to improve the reliability of embedded sensors.
