Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 1,   Pages 215-228 doi: 10.1007/s11709-019-0595-6

Abstract: approach that combines the extended finite element method associated with variable-node elements and cohesivezone model is developed.By using a new enriched technique based on sign function, the proposed model using 4-node quadrilateralalso allows modeling the equal stresses at both sides of the crack in the crack-tip as assumed in the cohesivemodel, and is able to simulate the arbitrary crack-tip location.

Strategic Study of CAE 2002, Volume 4, Issue 5,   Pages 53-58

Abstract:

Nonlinear fracture behaviors of concrete materials are mainly caused by the cohesive stress alongthe fracture process zone.Based upon concrete fracture properties and the analytical model of crack with cohesive forces, two simpleformulae concisely expressing the cohesive stress distribution are presented through analyzing characteristicsof the cohesive force distribution function.
