Is rotined, that at definite boundary conditions in definite ranges of change of solution of a corner an angular point, from which one two straight lines of slips modelling initial plastic prefracture zone leave remains by a stress raiser, that is why instead of widely practiced now model with two slip lines, it is necessary to use other model of an initial zone prefracture. As this new model of an initial zone prefracture near to an angular point it is offered to use model "trident". Product Description popup.authors popup.nrat_date 2020-04-02 Close
