up to know the failure load assessment of cracked polymer mortar plates is still not fully understood, especially when complex fracture modes are involved: The present paper is concerned with the failure analysis of cracked polymer mortar plates is combined mode I and II. The Brazilian disk, a classic mixed mode fracture test specimen, was adopted for the experimental characterisation of the crack initiation. Digital Imagen Correlation (DIC) method was used to obtain the full-field displacement close to the crack tip and a failure criterion is proposed with a good correlation with the experimental results.
