5 Finite Element Methods Using A Zero Thickness Interface Elements 1 introduction the prediction of crack initiation and propagation of quasi brittle materials such as rocks or concrete is an essential topic in various engineering fields such as structural or geotechnical engineering. The formulation of the problem is based on the discrete crack approach, in which each discontinuity is explicitly discretized by means of interface elements of zero thickness and with double nodes, which are equipped with the appropriate mechanical and diffusive constitutive laws. The zero thickness cohesive element approach for arbitrary crack propagation has a deficiency of introducing artificial compliance to the model, especially when cohesive elements are inserted into every element interfaces. For this purpose, this paper describes a methodology based on the use of zero thickness interface elements equipped with a fracture based constitutive law, combined with configurational mechanics theory.

Zero Thickness Interface Model Defining The Equivalent Interface в B C The zero thickness cohesive element approach for arbitrary crack propagation has a deficiency of introducing artificial compliance to the model, especially when cohesive elements are inserted into every element interfaces. For this purpose, this paper describes a methodology based on the use of zero thickness interface elements equipped with a fracture based constitutive law, combined with configurational mechanics theory. This document discusses using zero thickness interface elements to model cracks in finite element analysis. it introduces interface elements and cohesive crack models, describes how to formulate and implement them in finite element codes, and provides some examples of their use. The model is based on the finite element method, and uses zero thickness interface elements equipped with a fracture based constitutive formulation to represent cracks. In this work, the traditional cohesive interface model is extended to handle cracks in the context of three dimensional shell elements.
