Constant Strain Triangle Element with Embedded Discontinutity Based on Partition of Unity
Original language description
The present paper illustrates formulation and implementation of a simple constant strain triangle with embedded displacement discontinuity intended for the modeling of localized damage. To arrive at such an element the partition of unity property of finite element shape functions is used to introduce the displacement discontinuity into the finite element basis. The similarity between standard two dimensional interface element and the one based on the present formulation is used to test the behavior of the new element both in bending and tension problems by examining interfacial tractions developed along a predefined interface with a given interfacial stiffnesses. The influence of the selected numerical integration rule is also explored
