Numerical Simulation of Brittle Material Breakage with Cracks
Zhang Ying (Dept. Basic Sciences,Beijing 100044)
As a kind of numerical simuilation methed for brittle material breakage,material breakage takes the element Gauss node's damage as distinguishing rule. The contribution of Gauss node to element stiffness should be removed. So the residual stress of Gauss node can be brought to the structure as the load by element node. Some examples show that this method can be regarded as an effective method of analyzing brittle material breakage.
