摘要：

Up to now 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 in 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 Image 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.
