On mixed-mode fracture mechanics models for contact area reduction under shear load in soft materials

On mixed-mode fracture mechanics models for contact area reduction under shear load in soft materialsA Papangelo, M Ciavarella - arXiv preprint arXiv:1809.10676, 2018The fundamental problem of friction in the presence of macroscopic adhesion, as in 
soft bodies, is receiving interest from many experimentalists. Since the first fracture 
mechanicspurely brittle'model of Savkoor and Briggs, models have been proposed .......  The paper is under review on a well known journal, so please make comments for possible improvements if you like.
