This paper concerns the effect of friction on crack propagation for the centrally cracked Brazilian disk under diametric forces by using a modified finite element method.It shows that the mode II stress intensity factor decreases obviously with the increase of friction after the crack is closed, while friction has no influence on the stress intensi
The food industry has become interested in the development of innovative biomaterials with antioxidant and antimicrobial properties.Although several biopolymers have been evaluated for food packaging, the use of polyphenolic coatings has been unexplored.The purpose of this work was to develop an antioxidant and antimicrobial coating for food packag
Introduction.When a rockfill dam with a concrete face is constructed on the earth foundation, its seepage control facility is complemented by a cutoff wall and an apron.Together they represent a complicated integrated seepage control facility.The performance of an integrated seepage control facility gains relevance, which is proven by the experienc
