Abstract:The automatization of crack expand simulation is carried out by the programmer, using the simulation technique of singular unit, base on the ANSYS software. The nodes are dispersed by crack front. The singular unit is using to radiate from the nodes. The restriction is used at the edge of model. The stress intensity factor is worked out. The expansion ratio is confirmed. Then the displacement of crack expansion of the nodes is resolved. The way of expansion of crack front is orthogonal. The semi-ellipse curve … Show more
